[目的] 本研究对中药注射液治疗肺心病的系统评价/Meta 分析进行再评价,以期为临床应用中药注射液提供循证支持。[方法] 计算机检索中国知网(CNKI)、中国生物医学文献数据库(SinoMed)、Embase、The Cochrane Library等 8 个中英文数据库,检索年限为建库至 2023 年 3 月,搜集中药注射液治疗肺心病的系统评价/Meta 分析。分别使用AMSTAR-2、PRISMA 2020、GRADE 系统对纳入研究的方法学质量、报告质量及证据质量进行评价。[结果] 共纳入26 篇系统评价/Meta 分析,涉及 16 种中药注射液,29 个结局指标。AMSTAR-2 评价结果表明,纳入文献的方法学质量整体较低,无中、高质量文献,条目 2(前期方案)、3(研究类型选择原因)、4(文献检索)、8(研究特征描述)、10(资助来源)具有明显缺陷。PRISMA 2020 结果显示 8 个主题条目的报告完整度<50%,分别为检索策略、方法综合、可信度评价、结果综合、证据可信度、注册与计划书、利益冲突和补充材料。GRADE 评估结果表明纳入研究中无高质量证据体,方法学质量低、结果不一致、存在发表偏倚是证据质量降级的主要因素。[结论] 基于现有证据,提示中药注射液治疗肺心病有效且基本安全,有助于纠正肺心病患者的缺氧状态、改善心室收缩和舒张功能、降低肺动脉压、改善血液流变学指标。但目前已发表系统评价/Meta 分析的方法学质量较低,文献报告存在一定缺陷,且证据质量等级不高,影响结果的可靠性。因此,未来需要更多高质量的临床研究和证据为中药注射液治疗肺心病的有效性和安全性提供循证支持。  相似文献

ObjectiveRecently, the effects of Baduanjin (a traditional Chinese mind-body exercise) on diabetes have attracted increasing attention, and relevant systematic reviews (SRs) have emerged. However, the qualities of these SRs vary markedly, and their conclusions are inconsistent, which is not conducive to guiding decision-making. We sought to assess the quality of these SRs and provide more evidence for diabetes treatment.MethodsA literature search was conducted in 7 databases from inception to December 1st, 2021. SRs of randomized controlled trials investigating the effects of Baduanjin were identified. A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR-2) checklist, Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement, and Grading of Recommendations Assessment, Development and Evaluation (GRADE) system were applied to evaluate the quality of the SRs.ResultsTen SRs were identified. All SRs were judged as critically low methodological quality by the AMSTAR-2 checklist. The total PRISMA score of the included SRs ranged from 15 to 21, and the mean score was 18.60 (1.90), indicating that all SRs had partial reporting deficits. Sixty outcomes were reported in the included studies, of which 25 (41.67%) were judged as low quality, and 34 (56.67%) as very low quality according to the GRADE system, indicating that the overall evidence quality of outcomes was not high.ConclusionBaduanjin seems to be an effective therapy for diabetes in improving glucose and lipid metabolism, mental health, quality of life, and waist-hip ratio (WHR). The overall quality of the SRs was less than optimal. This conclusion should be treated with caution, and researchers should conduct higher-quality clinical studies following AMSTAR-2checklist, PRISMA statement, and GRADE system in the future.  相似文献

BackgroundAcupuncture has been widely used to relieve migraine-related symptoms. However, the findings of previous systematic reviews (SRs) and meta-analyses (MAs) are still not completely consistent. Their quality is also unknown, so a comprehensive study is needed.ObjectiveTo evaluate the reporting and methodological quality of these MAs concerning acupuncture for migraine, and summarize evidence about the efficacy and safety of acupuncture for migraine.Search strategyPubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Chinese Biomedical Databases, Wanfang Data, and VIP databases were searched from inception to September 2020, with a comprehensive search strategy.Inclusion criteriaThe pairwise MAs of randomized controlled trials (RCTs) concerning migraine treated by acupuncture or acupuncture-based therapies, with a control group that received sham acupuncture, medication, no treatment, or acupuncture at different acupoints were included.Data extraction and analysisTwo independent investigators screened studies, extracted relevant data, and assessed reporting and methodological quality using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 and A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2), then all results were cross-checked. Spearman correlation test was used to evaluate the correlation between reporting and methodological quality scores.ResultsA total of 20 MAs were included in this study. The included MAs indicated that acupuncture was efficacious and safe in preventing and treating migraine when compared with control intervention. There was a high correlation between reporting and methodological quality scores (rs = 0.87, P < 0.001). The quality of the included SRs needs to be improved mainly with regard to protocol and prospective registration, using a comprehensive search strategy, summarizing the strength of evidence body for key outcomes, a full list of excluded studies with reasons for exclusion, reporting of RCTs’ funding sources, and assessing the potential impact of risk of bias in RCTs on MA results.ConclusionAcupuncture is an effective and safe intervention for preventing and treating migraine, and could be considered as a good option for patients with migraine. However, the reporting and methodological quality of MAs included in this overview is suboptimal. In the future, AMSTAR 2 and PRISMA tools should be followed when making and reporting an SR with MA.  相似文献

Nausea and vomiting are common and distressing adverse events of chemotherapy. This review focuses on the findings and quality of systematic reviews (SRs) of cannabinoids for chemotherapy‐induced nausea and vomiting (CINV). Review of SRs, a systematic literature search, was conducted in several electronic databases and included SRs evaluating cannabinoids for CINV in cancer patients. Methodological quality and quality of reporting were evaluated by AMSTAR and PRISMA, respectively. Initial search retrieved 2,206 records, and 5 SRs were included. On the basis of findings of the sole SR judged as high methodological quality, cannabinoids seem to be more effective than placebo, equal to prochlorperazine for reducing CINV, and to be preferred by patients. The response to different combinations of antiemetic agents seems to be equal to 1 antiemetic alone. The average of AMSTAR score was 5, and the average of PRISMA score was 13.2. Cannabinoids represent a valuable option for treating CINV, despite the adverse events related to treatment, such as drowsiness and cognitive impairment. There is no good quality evidence to recommend or not the use of cannabinoids for CINV. More studies are still needed to evaluate the effectiveness of cannabinoids when compared with modern antiemetics.  相似文献

Background:Polycystic ovary syndrome(PCOS) is the primary cause of anovulatory infertility, bringing serious harm to women’s physical and mental health. Acupuncture may be an effective treatment for PCOS. However, systematic reviews(SRs) on the efficacy and safety of acupuncture for PCOS have reported inconsistent results, and the quality of these studies has not been adequately assessed.Objective: To summarize and evaluate the current evidence on the efficacy and safety of acupuncture for PCOS,...  相似文献
