Statistical Analysis
Sample-sized weighted pooled baseline patient and procedural
characteristics were calculated for each hypothermia regimen group.
Early event risks were pooled using inverse variance weighting and
pooled in a random-effects model using the Der Simonian and Laird method
to estimate the between-study variance 13.
Random-effect meta-analysis was performed using ‘metafor’ and ‘meta’
packages in R (version 4.0.5., R Project for Statistical Computing).
