In 2021, the Diagnostic Test Accuracy database (DiTA) was searched over 25,000 times by users in 147 countries.

Although DiTA contains more primary diagnostic test accuracy studies than systematic reviews of such studies, the most commonly accessed articles by DiTA users were primarily reviews. This means that many physiotherapists are using the most condensed forms of high-quality evidence to guide their practice. Reviews synthesise the results of all available studies about a particular diagnostic test for a specific health condition.

The top 10 articles accessed in DiTA during 2021 were:
