متن کاملInteractive visualisation for interpreting diagnostic test accuracy study results
Information about the performance of diagnostic tests is typically presented in the form of measures of test accuracy such as sensitivity and specificity. These measures may be difficult to translate directly into decisions about patient treatment, for which information presented in the form of probabilities of disease after a positive or a negative test result may be more useful. These probabi...

متن کاملCochrane diagnostic test accuracy reviews
In 1996, shortly after the founding of The Cochrane Collaboration, leading figures in test evaluation research established a Methods Group to focus on the relatively new and rapidly evolving methods for the systematic review of studies of diagnostic tests. Seven years later, the Collaboration decided it was time to develop a publication format and methodology for Diagnostic Test Accuracy (DTA) ...
متن کاملDiagnostic accuracy studies : how to report and analyse inconclusive test
The results of studies on diagnostic test accuracy are often reported as a 2×2 classification matrix, in which test results are presented as a dichotomy and a reference standard is used to categorise individuals as with or without disease. This facilitates the calculation of many popular statistics used to summarise the discriminatory performance of tests (such as sensitivity and specificity, p...
