Figure 2. Adjusted Kaplan-Meier Curves for 10-Year Mortality and Recurrence by Demographic Subgroups.

The inverse probability weight (IPW)–adjusted Kaplan-Meier curves compare the probability of survival and being free from recurrence within 10 years after acute myocardial infarction (AMI) by subgroups. Variables used to estimate the IPW included the demographic, admission, and comorbidity characteristics in Table 1. All patients had a 10-year follow-up.
