For Yes Must have reported on the sources of funding for individual studies included in the review. Note: Reporting that the reviewers looked for this information but it was not reported by study authors also qualifies Yes No If meta-analysis was performed did the review authors use appropriate methods for statistical combination of results? RCTs For Yes: The authors justified combining the data in a metaanalysis AND they used an appropriate weighted technique to combine study results and adjusted for heterogeneity if present. AND investigated the causes of any heterogeneity Yes No No meta-analysis conducted For NRSI For Yes: The authors justified combining the data in a metaanalysis AND they used an appropriate weighted technique to combine study results, adjusting for heterogeneity if present AND they statistically combined effect estimates from NRSI that were adjusted for confounding, rather than combining raw data, or justified combining raw data when adjusted effect estimates were not available AND they reported separate summary estimates for RCTs and NRSI separately when both were included in the review Yes No No meta-analysis conducted
