In basic principle, all the above info needs to be furnished for every final result viewed as within the critique, together with both of those Positive aspects and harms. When you'll find a lot of results for entire info to get provided, results for An important outcomes must be included in the most crucial report with other data supplied as a web appendix.

Authors also needs to offer, for every meta-analysis, a evaluate of the consistency of the final results in the provided reports which include I2 (heterogeneity, see box 6); a assurance interval can also be supplied for this evaluate.
Examples End result amount: “The meta-analysis described in this article brings together details throughout reports so that you can estimate cure consequences with web a lot more precision than is achievable in an individual study.
Authors ought to explicitly mention In the event the planned main results cannot be offered as a result of deficiency of knowledge.
