About IDAG

IDAG is an independent registry for the prospective registration and publication of protocols for systematic reviews, meta-analyses and other structured evidence syntheses, covering both human and preclinical animal research.

Objectives

Transparency

Publicly record what a review intends to do, so readers can compare the plan with the final report.

Prospective registration

Encourage registration before screening and data extraction, when decisions are still unbiased by results.

Methodological rigour

Prompt authors to specify questions, eligibility criteria, outcomes, bias assessment and synthesis methods in advance.

Visibility

Make planned and ongoing evidence syntheses discoverable to researchers, funders and decision-makers.
