Quality assessment

Quality measure Details Score Comments
QA question 1 Are the research questions and inclusion criteria for the review clearly delineated? 1 = “Yes” = Who (Population), What (Intervention, Comparator group, Outcome), Where and When described. general but concrete description of aims
QA question 2 Did the report of the review contain an explicit statement that the review methods were established prior to the conduct of the review and did the report justify any significant deviations from the protocol? 0 = ”No” = research question and inclusion criteria not outlined in detail. not provided
QA question 3 Did the review authors explain their selection of the study designs for inclusion in the review? 0.5 = “Can’t answer / not sure / partially” =Cannot decide between “yes” and “no”, basing on the information provided in the paper. any peer-reviewed articles for the scoping/mapping purpose
QA question 4 Did the review authors use a comprehensive literature search strategy? 0 =”No” = no information on search strategy, or not fulfilling criteria for “Yes” and “Partially”. two+ databases?
QA question 5 Did the review authors perform study selection in duplicate? 0.5 = “Can’t answer / not sure / partially” = Cannot decide between “yes” and “no”, basing on the information provided in the paper. two researchers for the full-text screen
QA question 6 Did the review authors perform data extraction in duplicate? 1 = “Yes” = either ONE of the following: at least two reviewers achieved consensus on which data to extract from included studies OR two reviewers extracted data from a sample of eligible studies and achieved good agreement (at least 8 %), with the remainder extracted by one reviewer. two reviewers
QA question 7 Did the review authors provide a list of excluded studies and justify the exclusions? 0 =”No” = No list of studies excluded at a full-text stage. not provided
QA question 8 Did the review authors describe the included studies in adequate detail? 0 =”No” = no, or partial description of the included studies not provided
QA question 9 Did the review authors use a satisfactory technique for assessing the risk of bias (RoB) in individual studies that were included in the review? 0 =”No” = no mention of RoB assessment of individual included studies. not provided
QA question 10 Did the review authors report on the sources of funding for the studies included in the review? 0 =”No” = no report of the sources of funding for individual studies included in the review. not provided
QA question 11 If meta-analysis was performed did the review authors use appropriate methods for statistical combination of results? N/A no meta-analysis
QA question 12 If meta-analysis was performed, did the review authors assess the potential impact of RoB in individual studies on the results of the meta-analysis or other evidence synthesis? N/A no meta-analysis
QA question 13 Did the review authors account for RoB in individual studies when interpreting/ discussing the results of the review? 0 =”No” = no discussion of the potential impact of RoB in individual studies. not provided
QA question 14 Did the review authors provide a satisfactory explanation for, and discussion of, any heterogeneity observed in the results of the review? 1 = “Yes” = There was no significant heterogeneity in the results OR if heterogeneity was present the authors performed an investigation of sources of any heterogeneity in the results and discussed the impact of this on the results of the review. discussed methodological factors
QA question 15 If they performed quantitative synthesis did the review authors carry out an adequate investigation of publication bias (small study bias) and discuss its likely impact on the results of the review? N/A no meta-analysis
QA question 16 Did the review authors report any potential sources of conflict of interest, including any funding they received for conducting the review? 0 = ”No” = The authors did not provide statement on competing interests and funding sources, and how they managed potential conflicts of interest. not provided
Quality index Overall rating (Quality Index) assigned to each SR, highlighting whether major concerns arose during quality assessment that may affect overall conclusions of a SR: A = Minimal flaws; B = Some flaws; C = Major flaws in many aspects of the review. C no protocol, very little details, bias might be present
Suggested review type Actual review type:systematic map, systematic review, rapid review, scoping review, narrative review, etc. scoping review N/A
Risk of bias level How likely are the main conclusions of the review to be biased? Basing on review type and quality index and quality_index_comment assign: high moderate or low risk? medium no protocol; search details missing; included studies with unknown bias levels; no statement on conflict of interests/funding
