Table 4 Items relevant to reporting results for a meta-analysis from the Preferred Reporting Items for Systematic reviews and Meta-Analysis for Ecology and Evolutionary Biology (PRISMA-EcoEvo; [96])
Item | Description |
|---|---|
20: Sample sizes and study characteristics | “Report the number of studies and effect size for data included in meta-analyses and subsets of data included in meta-regressions. Provide a summary of kye characteristics for reported outcomes (either in text or figures; e.g., one quarter of effect sizes reported for vertebrates and the rest invertebrates) and their limitations (e.g., collinearity and overlaps between moderators), including characteristics related individual study quality (risk of bias).” |
21: Meta-analysis | “Provide a quantitative synthesis of results across studies, including estimates for the main effect size, with confidence/credible intervals.” |
22: Heterogeneity | “Report indicators of heterogeneity in the estimated effect (e.g. I2, tau2 and other variance components).” |
23: Meta-regression | “Provide estimates of meta-regression slopes (i.e. regression coefficients) for all variables that were assessed for their contribution to heterogeneity. Include confidence/credible intervals, and report interactions if they were included. Describe outcomes from model selection, if done (e.g. R2 and AIC).” |
24: Outcomes of publication bias and sensitivity analysis | “Provide results for the assessments of the risks of bias (e.g. Egger’s regression, funnel plots) and robustness of the review’s results (e.g. subgroup analyses, meta-regression of study quality, results from alternative methods of analysis, and temporal trends)” |
