Diagnostic test accuracy review

A diagnostic test accuracy review is a specialised systematic review that focuses on identifying, summarising, and synthesising evidence on the performance (accuracy) of a specific diagnostic test. It evaluates the test’s ability to correctly identify individuals with the target condition (sensitivity) and those without the condition (specificity). This type of review can be used to generate a receiver operating characteristic curve (ROC curve; sensitivity vs specificity) for the test, investigate reasons for variability in reported accuracy across studies, and compare the accuracy of the test with other diagnostic tests for the same condition.
