Introduction. In neuropsychological research and clinical practice, a large battery of tests is often administered to determine whether an individual deviates from the norm. We formulate three criteria for such large battery normative comparisons. First, familywise false-positive error rate (i.e., the complement of specificity) should be controlled at, or below, a prespecified level. Second, sensitivity to detect genuine deviations from the norm should be high. Third, the comparisons should be easy enough for routine application, not only in research, but also in clinical practice. Here we show that these criteria are satisfied for current procedures used to assess an overall deviation from the norm—that is, a deviation given all test results. However, we also show that these criteria are not satisfied for current procedures used to assess test-specific deviations, which are required, for example, to investigate dissociations in a test profile. We therefore propose several new procedures to assess such test-specific deviations. These new procedures are expected to satisfy all three criteria. Method. In Monte Carlo simulations and in an applied example pertaining to Parkinson disease, we compare current procedures to assess test-specific deviations (uncorrected and Bonferroni normative comparisons) to new procedures (Holm, one-step resampling, and step-down resampling normative comparisons). Results. The new procedures are shown to: (a) control familywise false-positive error rate, whereas uncorrected comparisons do not; (b) have higher sensitivity than Bonferroni corrected comparisons, where especially step-down resampling is favorable in this respect; (c) be user-friendly as they are implemented in a user-friendly normative comparisons website, and as the required normative data are provided by a database. Conclusion. These new normative comparisons procedures, especially step-down resampling, are valuable additional tools to assess test-specific deviations from the norm in large test batteries. 相似文献

Subtypes of antimitochondrial antibodies in primary biliary cirrhosis before and after orthotopic liver transplantation 总被引:1,自引:0,他引:1

Antimitochondrial antibodies are markers for primary biliary cirrhosis and probably reflect a specific defect in immunoregulation underlying this disease. Antimitochondrial antibodies and their primary biliary cirrhosis-specific subtypes were tested before and up to 6 years after orthotopic liver transplantation. Sera from 31 consecutive patients were tested, 15 patients had primary biliary cirrhosis and 16 non-primary biliary cirrhosis. Antimitochondrial antibodies were investigated under code by immunofluorescence, and primary biliary cirrhosis-specific subtypes were determined by radioimmunoassay (anti-p62, anti-p48) and complement fixation test (anti-M2, anti-M4, anti-M8). Before orthotopic liver transplantation, antimitochondrial antibodies were detected by immunofluorescence in 13 of 15 patients with primary biliary cirrhosis. Of these patients, 12 were positive for anti-p62 and 8 for anti-p48. Ten patients were positive for anti-M2, 4 patients for anti-M4 and 7 patients for anti-M8. Two primary biliary cirrhosis patients and all non-primary biliary cirrhosis patients were negative with all tests. One month after orthotopic liver transplantation, antimitochondrial antibodies titers declined or became negative by antimitochondrial antibodies immunofluorescence, 3 patients became negative by radioimmunoassay for anti-p62 and 1 for anti-p48. With complement fixation test, 4 patients became negative for anti-M2, 2 for anti-M4 and 4 for anti-M8. Antimitochondrial antibody titer reduction observed 1 month after orthotopic liver transplantation remained unchanged in most sera during the following years. A rise was observed in two patients after 4 and 5 years.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献
