Components of GRADE-CERQual approach (Lewin et al., 2018b, p. 5)

1. Methodological limitations	‘The extent to which there are concerns about the design or conduct of the primary studies that contributed evidence to an individual review finding’ (Lewin et al., 2018a, p. 1)
2. Coherence	‘An assessment of how clear and cogent the fit is between the data from the primary studies and a review finding that synthesizes that data’ (Lewin et al., 2018a, p. 1)
3. Adequacy	‘An overall determination of the degree of richness and quantity of data supporting a review finding’ (Lewin et al., 2018a, p. 1)
4. Relevance	‘The extent to which the body of data from the primary studies supporting a review finding is applicable to the context specified in the review question’ (Lewin et al., 2018a, p. 1)
