Build_Status CRAN_Status_Badge CRAN_Download_Badge CRAN_Download_Badge_All

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.
