Regression Standardized Survival and Difference in Survival

(Upper panel) The curves represent the estimated survival and 95% CI if the population either had received permanent pacemaker implantation or had not received permanent pacemaker implantation, respectively. For example, if the entire population had received a permanent pacemaker implantation, the estimated population survival at 17 years would be 47%. (Lower panel) Estimated difference in survival (95% CI) between the pacemaker and no pacemaker groups.
