The data in the table are the adjusted Kaplan-Meier estimates with the 95% CI. The CR group consists of patients who were referred to and attended at least one session. The No-CR group consists of patients who were referred to but did not attend any sessions.
CR, cardiac rehabilitation; HR, hazard ratio; CI, confidence interval; MACCE, all-cause mortality, myocardial infarction, stroke, or repeat revascularization.
