O’Neill et al. [12] | To assess the utility of an acronym, place of residence, race/ ethnicity/culture/language, occupation, gender/ sex, religion, education, socioeconomic status, and social capital (“PROGRESS”) to guide the conceptualization of disadvantage, data extraction, and to inform equity analyses in systematic reviews. Aimed at reviewers, researchers and users | Authors demonstrate how an existing framework PROGRESS, the framework for the PRISMA Equity Extension, can be applied to systematic reviews | Asks reviewers to consider variations in health across 8 factors: place of residence, race/ethnicity/culture/ language, occupation, gender/sex, religion, education, socioeconomic status and social capital. For each PROGRESS factor, examples are provided that demonstrate differences in burden of disease and an effective intervention that could reduce that burden. | Strengths: • Considers multiple equity dimensions Limitations: • Limited examples provided further detail on how reviewers can operationalise individual items is required • Not evaluated • Not open access |

Oxman et al. [28] | To present a structured approach to considering the impacts of policy and programme options on inequities, to inform decisions about what options to implement and how to implement them. Aimed at users | Not reported | 4 questions that can be used to guide considerations when using systematic reviews regarding impacts on inequities. | Strengths: • Descriptive examples provided • Open access Limitations: • No information available on how the guidance was developed or evaluated. • Terminology used may not be widely accepted or understood • Greater detail required on how reviewers can operationalise the items |
Tugwell et al. [29] Ueffing E, et al. for the Campbell and Cochrane Equity Methods Group. [30] | To provide guidance on assessing equity for users and authors of systematic reviews of interventions. Aimed at reviewers, users and journal editors. | Development process: • 4 working sessions • Built on previous work by the members of the Measurement and Evidence Knowledge Network • Panel members reviewed the evidence and drafted guidance • Feedback and revision sought Who was involved: International leaders in systematic reviews and health equity, mixed methods experts, social scientists, economists, experts in systematic reviews, experts in public health and health equity, experts from low and middle income countries and policy advisers who use systematic reviews. Members of the Campbell and Cochrane Equity Methods Group and the Measurement and Evidence Knowledge Network | 7 recommendations underpinned by 16 checklist items. Examples provided | Strengths: • Wide range of expertise involved in development • Consensus-based •Descriptive examples provided •Addition of resources to signpost reviewers to sources of help when attempting to answer the questions. Limitations: • Terminology used may not be widely accepted or understood • Greater detail required on how reviewers can operationalise the items |
