Abstract
Background: Diagnostic test accuracy (DTA) systematic reviews synthesize data from primary diagnostic studies that have evaluated the accuracy of one or more index tests against a reference standard. DTA systematic reviews provide estimates of test performance, allow comparisons of the accuracy of different tests, and facilitate the identification of sources of variability in test accuracy.

Objectives: To develop PRISMA-DTA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) as a stand-alone extension of the PRISMA statement, modified to reflect the particular requirements for reporting DTA systematic reviews and meta-analyses, as well as PRISMA-DTA for abstracts.

Methods: We followed established standards for guideline development (EQUATOR Network). The PRISMA statement was used as a framework upon which to modify and add material. A group of 24 multi-disciplinary experts used a systematic review of existing reporting guidelines and methods articles, a three-round Delphi process, a consensus meeting, pilot testing, and iterative refinement to develop PRISMA-DTA. The final version of the PRISMA-DTA checklist was approved by the PRISMA-DTA group. Similar methods were followed to modify PRISMA for abstracts to generate PRISMA-DTA for abstracts.

Results: Systematic review (64 items) and Delphi feedback (six new items proposed and one item split into two) identified 71 potentially relevant items for consideration; the Delphi process reduced these to 60 items that were discussed at the consensus meeting. Following the meeting, piloting and iterative feedback was used to generate the 27-item PRISMA-DTA checklist. To reflect DTA-specific or optimal contemporary systematic review methods, eight of the 27 original PRISMA items were left unchanged, 17 were modified, two were added and two omitted. A 12-item PRISMA-DTA for abstracts was developed.

Conclusions: PRISMA-DTA provides specific guidance for reporting of DTA systematic reviews. PRISMA-DTA can facilitate transparent reporting of DTA reviews, and may assist evaluations of validity and applicability, enhance replicability of reviews, and make the results more useful for multiple stakeholders.
