| QA question 4 |
Did the review authors use a comprehensive literature search strategy? |
0.5 = “Can’t answer / not sure / partially” = searched at least 2 databases (relevant to research question), provided key word and/or general search strategy, justified publication restrictions (e.g., language). |
2 databases and references |
| QA question 5 |
Did the review authors perform study selection in duplicate? |
0 =”No” = only one reviewer involved in the study selection or no description how many reviewers participated in study selection. |

| 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. |

| 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. |
general discussion |

| 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. |
B |
no protocol, some details missing, some bias might be present |
| Suggested review type |
Actual review type:systematic map, systematic review, rapid review, scoping review, narrative review, etc. |
rapid 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; some search details missing |
