They may additionally supply vital information regarding applicability of proof, propose the possible effects of any important biases, and allow consideration, in a systematic manner, of many explanations for feasible differences of conclusions throughout reports.

For each study, the summary details for every intervention group are generally specified for binary outcomes as frequencies with and with no event (or as proportions for example twelve/forty five).
