## Figure 2.
Secondary outcome: mortality. Forest plot displays relative risk of death for all included studies and separately
for selective head cooling and whole body cooling studies. There is a significant
benefit of therapeutic hypothermia on the single outcome of mortality (RR: 0.75, 95%
CI: 0.59, 0.96, NNT: 11, 95% CI: 6, 100). The squares represent the point estimate
of treatment effect of each study with a horizontal line extending on either side
of the square representing the 95% confidence interval. The diamonds represent the
overall and subgroup relative risk estimate of the studies presented in the meta-analysis.
The widths of the diamonds represent the 95% confidence interval of the relative risk.
The vertical midline of the forest plot corresponding to a relative risk of 1 represents
a "no effect" line.
