dat.asat {metamedian}

Example data set: Comparing aspartate transaminase levels 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 aspartate transaminase (ASAT) levels of COVID-19 infected patients who died and those who survived. The unit of measurement for the ASAT levels is U/L. The rows in the data set correspond to the primary studies. Compared to the "raw" version (i.e., dat.asat_raw), this data set excludes the primary study of Qi et al. (2021) due to its small sample size in the nonsurvivor group.

Usage

dat.asat

Format

A data frame with 26 rows and 13 columns:

author	first author of the primary study and the journal name.
n.g1	number of subjects (nonsurvivor group).
q1.g1	first quartile of the ASAT levels (nonsurvivor group).
med.g1	median ASAT level (nonsurvivor group).
q3.g1	third quartile of the ASAT levels (nonsurvivor group).
mean.g1	mean ASAT level (nonsurvivor group).
sd.g1	standard deviation of the ASAT levels (nonsurvivor group).
n.g2	number of subjects (survivor group).
q1.g2	first quartile of the ASAT levels (survivor group).
med.g2	median ASAT level (survivor group).
q3.g2	third quartile of the ASAT levels (survivor group).
mean.g2	mean ASAT level (survivor group).
sd.g2	standard deviation of the ASAT levels (survivor group).
