Abstract Objectives To generate a comprehensive bank of systematic review (SR) reporting items to inform an update of the PRISMA 2009 statement. Methods We searched the EQUATOR Network library in May 2019 to identify all reporting guidelines for SRs that were published after 2009, regardless of the scope of the guideline. We also conducted a selective review of four guidance manuals for SRs, three tools for assessing risk of bias in SRs, six meta-research studies evaluating the reporting quality of SRs using a tailored checklist, and five reporting guidelines for other study designs. One author screened and selected sources for inclusion, extracted reporting guidance from sources, and mapped guidance against the PRISMA 2009 checklist items. Results We included 60 sources providing guidance on reporting of SRs and meta-analyses. From these, we collated a list of 221 unique reporting items. Items were categorised into title (four items), abstract (10 items), introduction (12 items), methods (111 items), results (61 items), discussion (12 items), funding and conflicts of interest (4 items), administrative information (3 items), and data availability (4 items). This exercise generated 175 reporting items that could be added to the guidance in the PRISMA 2009 statement. Conclusions Generation of a comprehensive item bank through review and mapping of the literature facilitates identification of missing items, and those needing modification, which may not otherwise be identified by the guideline development team or from other activities commonly used to develop reporting guidelines.
