Publication rate of abstracts presented at the annual meeting of the American Urological Association

OBJECTIVE: To determine the rate and time-course of peer-reviewed publication of abstracts presented at the annual meetings of the American Urological Association (AUA). METHODS: All abstracts presented at the annual meetings of the AUA from 1998 to 2000 were searched in the PubMed database. To assess any significant predictors of ultimate peer-reviewed publication, abstract number, meeting year, presentation type (podium vs poster), type of research (basic vs clinical), date of publication and session name (i.e. prostate cancer: advanced) were entered into a database. RESULTS: The overall rate of publication was 37.8%. Survival analysis indicated that most abstracts were published within 2 years of their respective meetings. Univariate and multivariate techniques showed that none of the tested covariates were significant predictors of publication. CONCLUSIONS: Information presented at the AUA annual meetings should be carefully considered by physicians before implementation into their clinical practice. Researchers are encouraged to publish their data.     

What is the ultimate fate of presented abstracts? The conversion rates of presentations to publications over a five-year period from three North American plastic surgery meetings

BACKGROUND:

Advancements in clinical decision-making are influenced by presentations made at scientific conferences or publications in journals with extensive readership. However, many ideas shared at annual conferences fail to be published, and most surgeons attend these meetings only sporadically.

OBJECTIVE:

To quantify the conversion rates of meeting presentations to publications in North American plastic surgery.

METHODS:

MEDLINE (OvidSP) and PubMed databases were cross-referenced with abstracts accepted for podium presentation at the Canadian Society of Plastic Surgeons, American Society of Plastic Surgeons, and American Association of Plastic Surgeons annual meetings from 2003 to 2007. Parameters reviewed included publication rate, time to publication, subspecialty, trial type, publication journal and journal impact factor.

RESULTS:

Over the five-year study period, 45.00% of the 888 presentations were published in peer-reviewed journals. The mean time to publication was 22 months (range 1.00 to 85.90 months). In total, 57.00% of the 400 publications appeared in Plastic and Reconstructive Surgery; 47.20% of publications were case series study design. The majority of publications were of the reconstruction subspecialty (31.00%). Abstracts from the American Society of Plastic Surgeons had the highest conversion rate (57.70%). Publications based on abstracts presented at the American Association of Plastic Surgeons had the highest mean journal impact factor (2.33). The Canadian Society of Plastic Surgeons had the highest total number of publications (n=161).

CONCLUSIONS:

From the three North American annual general meetings reviewed, there was a modest conversion rate of mainly reconstructive case series published predominantly in a single journal, Plastic and Reconstructive Surgery. Several years often pass from the genesis of a research hypothesis to final publication, and because the majority of presentations fail to be published, presentations should be observed with a critical eye given the more stringent peer review process and time required for final publication. In an effort to improve conversion rates, departments and faculty members must foster a culture that prioritizes publication.     

Publication rates of abstracts presented at annual musculoskeletal tumor society meetings

Beware of the unpublished abstract! What is the publication rate of abstracts presented at Musculoskeletal Tumor Society meetings, and how does this compare with other orthopaedic and medical meetings? Three hundred thirty-six podium presentations from six annual meetings were identified and their publication was searched at a minimum of 3 years after the event. An effort was made to determine what percent of these abstracts eventually were published in a peer-reviewed journal. It was determined that 137 abstracts were published for a publication rate of 41%. The average time between presentation at the meeting and publication was 21.8 plus or minus 13.5 months. The published articles appeared in 48 peer-reviewed journals. The rate of publication and time until publication was similar to other orthopaedic meetings and to other medical disciplines. Changes to the cohort, title, or authors occurred in approximately (1/3) of the published articles compared with the abstracts. These results suggest that for various reasons the majority of presented material at Musculoskeletal Tumor Society meetings may not survive peer review and may not be scientifically valid.     

The publication rates of presentations at major Spine Specialty Society meetings (NASS, SRS, ISSLS)

STUDY DESIGN: A review of all the presentations at three major spine specialty meetings held over a 3-year period. OBJECTIVES: To determine the rate of publication in peer-reviewed journals after presentations at major spine meetings conducted annually by the following three organizations: North American Spine Society (NASS), Scoliosis Research Society (SRS), and International Society for the Study of the Lumbar Spine (ISSLS). SUMMARY OF BACKGROUND DATA: The rate of publication for presentations at national and international meetings has been determined for medical and surgical subspecialties. This rate has been used to judge the quality of the content of the meetings and to determine the validity of the research presentations. METHODS: All presentations either in poster or oral presentation form were entered into a database covering a 3-year period for spine specialty meetings conducted annually by the following three organizations: NASS 1990 to 1992, SRS 1991 to 1993, and ISSLS 1991 to 1993. A computer search for each abstract was performed with the Melvyl Medline Plus database to determine if the abstract had been published in a peer-reviewed journal from 1990 to the end of 1997. Publication rates for presentations at these three meetings were determined over a 3-year period. RESULTS: A total of 1186 abstracts were listed over a 3-year period in the final programs of these three meetings for the years 1991 to 1993 (SRS, ISSLS) and 1990 to 1992 (NASS). Of these 1186 abstracts, 516 were published in peer-reviewed journals, giving an overall publication rate of 43.5%. The publication rates for the three different meetings (NASS, SRS, ISSLS) were similar, with values of 40%, 47%, and 45% respectively. More than 90% of the publications resulting from these meetings were published within a period of 4 years from the data of the meeting. CONCLUSIONS: The publication rates of presentations at three major spine specialty meetings are high and quite comparable with the publication rates of meetings in other medical subspecialties. This reflects the high quality of the meeting programs and validates their selection process.     

English publication rate of 3,205 abstracts presented at the Annual Meeting of the Japanese Orthopaedic Association and the Annual Research Meeting of the Japanese Orthopaedic Association

Background

Previous studies reported that the publication rate of abstracts presented at overseas meetings was around 50 %. The study objectives were to determine the rate of publication in English-language journals and the impact factor (IF) for all papers presented at the Annual Meeting of the Japanese Orthopaedic Association (JOA) and Annual Research Meeting of the Japanese Orthopaedic Association (JOAR), and to compare the publication rates and IFs from abstracts accepted for oral versus poster presentations.

Methods

Titles and first authors were identified for 1,676 abstracts of free papers accepted for presentation to the JOA in 2006 and 2007, and 1,529 abstracts to the JOAR from 2006 to 2008. We identified the associated journal publications by searching PubMed, and IFs were determined using the journal citation reports. The publication rates and IFs for papers accepted for oral versus poster presentations were compared using statistical analysis.

Results

The overall publication rate was 25.5 % from the JOA and 50 % from the JOAR. There were no significant differences in yearly publication rates, or between oral and poster presentations for each year. The average IFs for all publications from the JOA was 2.45 and that from the JOAR was 3.5. There were no significant differences in yearly IFs, or between oral and poster presentations for each year (P > 0.05).

Conclusions

The rate from JOAR was similar to publication rates for abstracts presented at overseas orthopedic meetings, however, the rate from JOA was half that of publication rates for abstracts presented at overseas orthopedic meetings, indicating that JOA may provide a below average contribution of new medical data to the international scientific community. No significant difference in publication rates between oral and poster presentations were found, and this suggests a need for improvement of the review system for the annual meeting and that review scores at the meetings did not predict the publication fate of abstracts.     

Are Abstracts Presented at the EAU Meeting Followed by Publication in Peer-Reviewed Journals?: A Critical Analysis

PURPOSE: Our goal was to assess the rate and time-course of peer-reviewed publication of abstracts presented at the European Association of Urology (EAU) Annual Meeting and to identify factors predictive of publication. METHODS: All abstracts accepted for presentation at the 2000 and 2001 EAU annual meetings were identified from the related published supplements in European Urology. The subsequent publication rate was estimated for the corresponding studies based on a scan of Medline covering a 5-year period following the meetings. We examined whether the following factors were associated with publication rate: research type, study subject, and country of origin. The analysis was performed using logistic regression of the dichotomous variable of publication versus non-publication and the candidate factors. RESULTS: Overall, 47.3% of 1406 abstracts presented at the EAU meetings were followed by publication in peer-reviewed journals. Pre-clinical research studies were more likely to be published than clinical studies (53.3% vs 45%, p<0.05). Prospective series were more likely to be published than retrospective ones (46.5% vs 32.2%, p<0.05). Studies presented at the meetings were mostly from Europe (74.2%). Mean time to publication was 8.6 months, and in most cases, the reports were published in The Journal of Urology and European Urology. The mean IF of journals where papers were published was 1.95. CONCLUSIONS: Almost half of the abstracts presented at the EAU are ultimately published in peer-reviewed journals, usually within 2 years after presentation. The publication rate differs significantly according to country of origin, study subject, and research type.     

Publication rates of presentations made at annual meetings of the American Orthopaedic Society for Sports Medicine and the Arthroscopy Association of North America

The purpose of this study was to determine the publication rates of presentations made at the annual meetings of 2 sports medicine specialty societies--the American Orthopaedic Society for Sports Medicine (AOSSM) and the Arthroscopy Association of North America (AANA). We created a database covering annual AOSSM meetings from 1990 to 1993 (4 years) and annual AANA meetings from 1991 to 1993 (3 years) and searched the Melvyl Medline Plus database for abstracts from 1990 through 1998 to determine which had been published in peer-reviewed journals. Of the 333 abstracts listed for the 1990 to 1993 meetings, 198 (59.5%) were published in peer-reviewed journals. Publication rates of the AOSSM and AANA meetings were 68.1% and 50.9%, respectively. The majority of articles were published in American Journal of Sports Medicine (40.1%) and Arthroscopy (30.3%). Publication rates of presentations made at meetings of these sports medicine specialty societies are high and exceed the publication rates associated with meetings of other medicine specialty societies.     

Conversion rates of abstracts presented at the Urological Society of Australia and New Zealand (USANZ) Annual Scientific Meeting into full-text journal articles

What's known on the subject? and What does the study add? It is well known that the transition of a presented abstract in a scientific meeting to a journal article improves the quality of the meeting and prevents an abstract being incorporated into meta‐analyses or practice guidelines without proper appraisal. This is the first analysis of USANZ Annual Scientific Meeting abstracts’ conversion to full publication. With relatively low publication rates compared to other international meetings, this review identifies the need for mechanisms to encourage USANZ researchers to convert their abstracts into published articles. The numbers and characteristics of the abstracts presented at the Annual Scientific Meetings (ASM) of the Urological Society of Australia and New Zealand (USANZ) that are converted to peer‐reviewed publications have not previously been analysed and published. We undertook a review of all abstracts presented at the USANZ ASM from 2005 to 2009. A PubMed search was performed between 15 June and 15 July 2012, using a search algorithm to identify the full‐text publications of the presented abstracts. Correlation between abstract characteristics and publication rate was then examined to distinguish the predictors for publications. Of 614 abstracts that were presented at USANZ ASM between 2005 and 2009, 183 papers were published, giving a publication rate of 29.80%. The papers were predominantly published in urological journals and were more likely to be published if they were presented by an international author or were retrospective studies or if basic science research. The mean (SD) time to publication was 14.46 (13.89) months and the mean Impact Factor of journals where papers were published was 2.90. The overall publication rate was relatively low compared with other urological meetings held in America and Europe. USANZ has a challenge of encouraging higher‐quality research from the authors to further enhance its publication rate and consequently the calibre of the meeting itself.     

The academic impact of 20 years of Irish otolaryngology society conferences

Background& Purpose: The Irish Otolaryngology Society (IOS) conference takes place annually. This conference allows surgeons and surgical trainees from Ireland and abroad an opportunity to showcase research ideas from their respective centres. This allows them to disseminate results, accept critique, and obtain different perspectives.We sought to examine research presented at the IOS meetings over 20 years. We aimed to analyse the publication rates, impact factor of journals, and citation rates of presented abstracts.MethodsAll oral presentations from IOS conferences were analysed between 2000 and 2019. Presentation titles and authors were searched using Pubmed, Google Scholar and Research Gate. We identified scientific publications which resulted from the research presented and the characteristics of each publication.ResultsOf 703 presentations made at the conferences spanning 20 years, 30.15% (n = 212) went on to publish their research averaging 19 citations per publication. Median time to publication was 2 years (-1-11). Each year there have been an increasing number of oral presentations with a declining publication rate.ConclusionThe Irish otolaryngology society meeting is a high-quality meeting with comparable publication rates to similar international conferences. Despite this, many presentations do not have any lasting impact as they are not published. The increasing pressure for trainees to rapidly present research projects without emphasis on completion of projects may explain the declining publication rate. Our study highlights the importance of completing high-quality research projects through publication. Meaningful conclusions from these projects can add to the body of knowledge and contribute to evidence-based practice.     

Fate of abstracts presented at the World Congress of Endourology: are they followed by publication in peer-reviewed journals?

PURPOSE: To estimate the acceptance rate of peer-reviewed journals, to describe the time course of subsequent full publication, and to identify those with characteristics associated with publication of the abstracts presented at the World Congress of Endourology (WCE). METHODS: All abstracts accepted for presentation at the 2001 and 2002 WCE meetings were identified from the published supplements to the Journal of Endourology. The subsequent publication rate for the corresponding studies was evaluated by scanning MEDLINE for the 5-year period after the meetings. RESULTS: Overall, 20.5% of the abstracts were followed by publication in peer-reviewed journals. Abstracts on transurethral, laparoscopic, and percutaneous procedures had the highest publication rates (25.5%, 25%, and 24.3%, respectively). Studies from North America had the highest publication rate (29.2%). The mean time to publication was 14.6 months. There was an 80% chance that an eventually published abstract was in print 2 years after presentation. The largest number of the reports were published in the Journal of Endourology (75 of 234; 32%), the official publication of the society that sponsors the WCE. CONCLUSIONS: Only one fifth of the abstracts presented at the WCE are ultimately published in peer-reviewed journals. Attendees should be aware of this limitation, and scientific committees should be encouraged to be more selective. Although presentation at major urological congresses constitutes an invaluable method for rapid scientific dissemination, abstracts contain data that usually are difficult to access and of questionable validity. In this respect, investigators are encouraged to publish their data.     

When will I see you again? The fate of research findings from international wound care conferences*

Medical conferences provide a forum for the rapid dissemination of research directly to health professionals and academics. However, the published record of poster and oral presentations from these meetings is usually limited to abstracts. We aimed to assess how many wound studies presented as conference abstracts were eventually published in journals and to identify the factors that predicted publication. The study was a retrospective review. We identified abstracts relating to oral and poster presentation from two large wound conferences. Following data extraction from the abstracts, a systematic search was conducted to examine if the research was subsequently published as a journal article. A time-to-event analysis was conducted to assess predictive associations between features of the research reported in the conference abstracts and time to full publication. In total, 492 abstracts from two European wound care conferences were identified (467 after exclusions). Of the abstracts included, 60% (279) were for posters and 40% (188) were for oral presentations. Over half of the abstracts (53%) reported results from case studies or case series design. In total, only 57 (12%) of the abstracts included resulted in a related publication. Analysis suggested that those studies reporting positive findings were significantly more likely to be published (hazard ratio 1.79, P= 0.001, 95% CIs 1.26-2.55). Few studies presented as conference abstracts at these two wounds conferences were subsequently published. This may be because of the low methodological quality of studies accepted for poster or oral presentation.     

Publication rate of General Surgery abstracts presented at the Royal Australasian College of Surgeons Annual Scientific Congress

Background

A commonly used metric for evaluating the quality and impact of presentations at a scientific meeting is the frequency with which the findings presented are published as full research papers in peer‐reviewed journals. The purpose of this study was to determine the full article publication rates of abstract presentations for General Surgery and related sub‐specialities at the Royal Australasian College of Surgeons Annual Scientific Congress (RACS ASC) from 2010 to 2014.

Methods

All General Surgical (including its sub‐speciality groups) abstracts presented at the RACS ASC from 2010 to 2014 were identified from the ANZ Journal of Surgery. We determined the rates of full paper publication, time to publication, journals of publication and specialty rates of conversion. Full article publications were identified using the PubMed, MEDLINE and Google Scholar databases.

Results

A total of 1386 abstracts were identified, of which 356 (26%) were converted to full paper publications. The number of abstracts presented annually increased from 206 in 2010 to 386 in 2014, but the percentage of abstracts converted to full paper publications did not follow any temporal trend. The majority (74%) of full papers were published within 2 years of the abstract presentation.

Conclusion

In total, 26% of General Surgery abstracts presented at the RACS ASC from 2010 to 2014 were converted to full paper publications. This could provide a baseline against which to judge the quality of presentations at other national General Surgical congresses, as well as at future RACS ASC meetings.     

Fate of Abstracts Presented at the Transplantation Society of Australia and New Zealand Annual Scientific Meetings

BackgroundThe numbers and characteristics of the abstracts presented at the Annual Scientific Meetings (ASM) of the Transplantation Society of Australia and New Zealand (TSANZ) that are converted to peer-reviewed publications have not been analyzed previously.MethodsAll abstracts presented at the TSANZ ASM from 2013 to 2017 were reviewed. A literature search was performed using a search algorithm to identify the full-text publications of the presented abstracts. Correlation between abstract characteristics and publication rate was then examined using Cox proportional hazards regression and Kaplan-Meier curves to distinguish the predictors for publication.Over the 5-year period, 576 abstracts were presented, with a total of 164 (28.6%) presentations converted to publications. The majority of publications occurred within the first 3 years, with the mean time to publication being 16.6 (standard deviation = 14.6) months. The median impact factor for published research was 4.74 (interquartile range = 3.06-5.58). Multivariate analysis identified clinical science papers, systematic reviews and surveys (likelihood ratio = 1.42, 5.02, and 2.01; P = .040, .000, and .010, respectively) as the most important predictors for publication.ConclusionsThe rate of abstracts presented at the TSANZ ASM over 5 years that were converted to publication in a peer-reviewed journal was 28.6%. Clinical papers, systematic reviews, and surveys were more likely to be published. An ongoing strict abstract selection process will contribute to improving conversion of abstracts into full-text peer-reviewed articles.     

Publication Rate of Abstracts Presented at the Shoulder and Elbow Session of the American Academy of Orthopaedic Surgery

Many shoulder and elbow abstracts presented at the American Academy of Orthopaedic Surgeons (AAOS) annual meeting are cited in the orthopaedic literature or are used to guide orthopaedic practice, but not all of these abstracts are submitted, survive peer review, or eventually are published. Presuming unpublished works have not been scientifically confirmed, one could question whether it is academically responsible to cite abstracts presented at the AAOS before they are peer-reviewed and published. To partly address this issue we determined the peer-reviewed publication rate for 558 abstracts (233 papers and 325 posters) presented at the shoulder and elbow sessions of the AAOS from 1999 to 2004. In April 2007, we searched the computerized database MEDLINE and PubMed for published articles based on these abstracts. We examined the published articles to assess publication rate, time to publication, change in contents, change in authors, and change in conclusions of abstracts. The overall publication rate in peer-reviewed journals was 58% (321 of 558), similar to other orthopaedic meetings and medical disciplines. We believe it is unacceptable to cite shoulder and elbow abstracts submitted to the AAOS because only slightly more than (1/2) (58%) of them are authenticated scientifically.     

Analysis of subsequent publication of scientific orally presented abstracts of the French National Congress of Radiology. Part II: Focus on the French abstracts

AimTo evaluate the publication rate of scientific abstracts that were presented orally at the 2008, 2009, and 2010 annual meetings of the French Society of Radiology by French radiologists, and to perform a French regional analysis.Material and methodsOrally presented abstracts were identified by examining online abstract books of the 2008, 2009, and 2010 annual meetings of the French Society of Radiology, and cross-checked by reviewing the paper version of abstracts for the same period. Only abstracts from French teams were selected. The administrative region of submission was noted for each abstract and for each region the total population, the number of active radiologists, the number of active members of the French Society of Radiology and the number of academic radiologists were noted. Imaging subspecialties were also noted.Results625 abstracts were identified resulting in 268 publications (publication rate: 43%). The median number of presentations and publications per region was 18 (range: 1–255) and 7 (range: 0–101), respectively. The ratio per million inhabitants was 7.5 and 3 respectively. The median number of presentations and publications per 100 active radiologists (respectively members of the FSR) was 7 and 3 (respectively 10 and 4). The median number of presentations and publications per academic radiologist were 2.6, and 1.2, respectively. The regional variations for each indicator were high (40–180%). Three subspecialties had a publication rate of more than 50%: thoracic imaging (58%), abdominal imaging (52%), and genitourinary imaging (51%).ConclusionThe publication rate of orally presented French scientific abstracts was high, with important variations according to the regions of origin and imaging subspecialties.     

Publication rates of abstracts presented at the 23rd (2013) and 24th (2014) National Turkish Orthopedics and Traumatology Congresses: We are not improving

ObjectivesThe aim of this study was to determine 1) the publication rates of podium and poster presentations from the 23rd (2013) and the 24th (2014) National Turkish Orthopedics and Traumatology Congresses in peer-reviewed journals and (2) compare these rates with publication rates from the 20th congress (2007) published previously. The secondary objective was to determine the time lag to publication and compare this data with the data from the 20th congress.MethodsAll abstracts from the scientific programs of the 23rd (2013) and the 24th (2014) National Turkish Orthopedics and Traumatology Congresses were identified and computerized PubMed searches were conducted to determine whether an abstract had been followed by publication of a full-text article in peer-reviewed journals. The time lag to publication was also noted.ResultsOf the 993 presentation abstracts (302 podium and 691 poster presentations) from the 23rd congress and of the 940 presentation abstracts (310 podium and 630 poster presentations) from the 24th congress, 278 (28%) and 234 (24.9%) were followed by a full-text article in peer-reviewed journals indexed by PubMed, respectively. The rates of publication of the podium and poster presentations were 39.4% (119/302) and 23% (159/691), respectively from the 23rd and 37.7% (117/310) and 18.6% (117/630), respectively from the 24th congresses. The mean time to publication of the abstracts from the 23rd congress was 12.8 ± 18.8 (median: 13, range: −140 to 47) months and the mean time to publication of the abstracts from the 24th congress was 11.1 ± 14.42 (median: 11, range: −73 to 39) months. Fifty (50/278, 18%) abstracts from the 23rd congress (mean −11, range: [−32]−[−1], median −5 months) and 37 (37/234, 15.8%) abstracts from the 24th congress (mean −10.4, range: [−73]−[−1], median −4 months) were published as full-text articles prior to the presentation at the congress.ConclusionThe vast majority of abstracts presented at 23rd (2013) and the 24th (2014) National Turkish Orthopedics and Traumatology Congresses were not followed by publication of a full-text article in peer-reviewed journals. The publication rates of the abstracts presented at these congresses did not improve when compared with the 20th (2007) congress.     

Scientific impact of women in academic surgery

OBJECTIVE: To evaluate the scientific impact of women in the surgical literature. METHODS: Gender of the principal investigator of every abstract presented at the 2002, 2003, and 2004 annual meetings of the Association for Academic Surgery and Society of University Surgeons was identified by internet search. Resulting publications were identified using PubMed. Journal impact factor and number of article citations were determined using ISI Web of Knowledge. RESULTS: The principal investigator's gender was identified for 649 (98.8%) of the 657 abstracts presented at the 2002--2004 AAS meetings. Women authored 9.1% of abstracts and 11.8% of total resulting publications. The publication rate of abstracts by women was significantly higher than that of men (69.5% versus 52.4%, P = 0.0132). There was a trend toward higher average impact factors of journals in which female authors published (3.265 versus 2.673, P = 0.0626). There was no significant difference in mean number of citations per publication. The principal investigator's gender was identified for all 337 (100%) abstracts presented at the 2002--2004 SUS meetings. Women authored 11.0% of abstracts and 11.2% of resulting publications. Publication rates and average citation numbers were similar for female and male authors. The average impact factors of journals in which women published were significantly higher (4.741 versus 3.348, P = 0.0082). CONCLUSIONS: Although women comprise a small proportion of principal investigators on abstracts presented at these conferences, the quality of their presented work is equal to or better than those of their male counterparts.     

Full publication of abstracts of randomised controlled trials published at International Continence Society meetings'

AIMS: To find out how many abstracts reporting randomised controlled trials (RCTs) that are submitted to scientific meetings of the International Continence Society (ICS) are later published in full, and any predictors of full publication. MATERIALS AND METHODS: The appropriate issues of "Neurourology and Urodynamics" and the Proceedings of the ICS for 1998 and 1999 were hand-searched for the abstracts reporting RCTs. Bibliographic databases (Cochrane Controlled Trials Register, MEDLINE, EMBASE, Healthstar, Psychlit, CINAHL) were searched, using the authors' names, to find full publications. Authors were contacted when no full publication was found to check that all full publications had been found. This was repeated for 1987. RESULTS: Sixty-three abstracts reporting RCTs were found in 1998 and 1999. Twenty-five of these (40%) were followed by full publication. The only characteristic that predicted full publication was the use of a no treatment control group. In 1987, 16 of 19 abstracts (84%) went on to be published in full. CONCLUSIONS: The rate of full publication of abstracts reporting RCTs submitted to recent ICS meetings is low. It is lower than the rate of 56% found in other meetings. As it is widely regarded as unethical not to publish in full, ICS members should make every effort to write-up studies for peer-reviewed publication.
