metamedian

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) doi:10.1002/sim.8013 and Ozturk and Balakrishnan (2020) doi:10.1002/sim.8738 can be applied to estimate the pooled median. In the two-group context, the methods of McGrath et al. (2020a) doi:10.1002/bimj.201900036 can be applied to estimate the pooled difference of medians across groups. Additionally, a number of methods (e.g., McGrath et al. (2020b) doi:10.1177/0962280219889080, Cai et al. (2021) doi:10.1177/09622802211047348, and McGrath et al. (2023) doi:10.1177/09622802221139233) are implemented to estimate study-specific (difference of) means and their standard errors in order to estimate the pooled (difference of) means. See McGrath et al. (in press) doi:10.1002/jrsm.1686 for a detailed guide on using the package.
