The standardized mean difference is a summary statistic reported in a meta-analysis when the same outcome is measured by different scales.Dichotomous data reporting is used to describe outcome data that are noncontinuous.The funnel plot is used to provide graphic representations of possible effect sizes.The mean difference is reported in a meta-analysis to identify the effect of an intervention but is appropriate only if the outcome is measured by the same scale in all the studies.
