Steps toward more complete reporting of systematic reviews of diagnostic test accuracy: Preferred Reporting Items for Systematic Reviews and Meta-Analyses of Diagnostic Test Accuracy (PRISMA-DTA).

Reporting standards in biomedical research have been shown to be suboptimal. The publication of the PRISMA statement has improved the completeness of reporting of systematic reviews, but several issues specific to diagnostic test accuracy are not included in the PRISMA statement. Therefore, a diagnostic test accuracy extension of the PRISMA statement, PRISMA-DTA, was created. This commentary addresses completeness of reporting in systematic reviews, the PRISMA-DTA statement, and strategies for optimal uptake of reporting guidelines.
