The metamedian
package implements several methods to meta-analyze studies that report the sample median of the outcome. When the primary studies are one-group studies, the methods of McGrath et al. (2019) can be applied to estimate the pooled median. In the two-group context, the methods of McGrath et al. (2020) can be applied to estimate the pooled raw difference of medians across groups.
