Kaplan—Meier curves were plotted to compare the incidences for both (A) cardiovascular events and (B) all-cause mortality in two patient groups, according to the Fibrosis-4 index of 2.51 in patients with high CHADS2 scores (≥2). Cardiovascular events included heart failure, myocardial infarction, unstable angina, and cardiac death.
