Primary validation studies

Distinct primary publications from the current diagnostic-accuracy audit. Reviews and repeated evaluations within one paper are not counted again. Overlapping cohorts have not all been reconciled. Read the counting rules and limitations.

No eligible diagnostic-accuracy paper is currently included in this audit. This does not mean the tool has never been validated. The source paper and other evidence on this profile may concern severity, reliability or another measurement purpose.
