It isn't ample to report occasion prices for each intervention group as percentages. The expected summary facts for steady outcomes are the necessarily mean, standard deviation, and sample size for each group. In assessments that take a look at time-to-event facts, the authors really should report the log hazard ratio and its common error (or assurance interval) for each incorporated study.
