Figure 1a. Probability of survival to one year following cardiac arrest, according to assigned treatment.

Figure 1a.

The two lines represent Kaplan-Meier survival rates from 0 to 365 days after cardiac arrest for patients in each study arm (p=0.045 for a log-rank test, stratified by age category and study, comparing survival distributions between treatment arms). Numbers above the x-axis represent numbers of patients at risk (alive and followed) in each study arm at each 30-day interval.
