The median is a descriptive statistic for continuous variable following abnormal distribution; hence, we aimed to explore the feasibility of meta-analysis based on median as effect size. Statistical basis and common implementation methods of meta-analysis using median as effect size are described and a metamedian package in R statistical software was applied to conduct meta-analysis and display of results based on median, heterogeneity in meta-analysis was also measured if suitable. This article provides another feasible solution to deal with median as effect size for meta-analysis.
