Implements the methods of McGrath et al. (2020) doi:10.1177/0962280219889080 and Cai et al. (2021) doi:10.1177/09622802211047348 for estimating the sample mean and standard deviation from commonly reported quantiles in meta-analysis. These methods can be applied to studies that report the sample median, sample size, and one or both of (i) the sample minimum and maximum values and (ii) the first and third quartiles. The corresponding standard error estimators described by McGrath et al. (2023) doi:10.1177/09622802221139233 are also included.
