Methodological, reporting and bibliometric characteristics of overviews synthesising health economic evidence.

This meta-research study will assess how overviews of systematic reviews of health economic evaluations are conducted and reported. In a broader sample that also includes overviews of other types of health economic evidence, we will describe common methodological and reporting practices and, where data permit, explore their associations with bibliometric characteristics. The findings will help determine whether an extension of the PRIOR reporting guideline is warranted and what it should cover.
