metamedian (version 1.1.0)

dat.age: Example data set: Comparing the age between COVID-19 survivors and nonsurvivors (cleaned version)

Description

A data set from the meta-analysis of Katzenschlager et al. (2021). Specifically, this data set corresponds to the meta-analysis comparing the age of COVID-19 infected patients who died and those who survived. The unit of measurement for the age values is years. The rows in the data set correspond to the primary studies. Compared to the "raw" version (i.e., dat.age_raw), this data set excludes the primary study of Qi et al. (2021) due to its small sample size in the nonsurvivor group.
