dat.age_raw

<p>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.</p>

datasets

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.
