Figure 1 Kaplan-Meier Event Curves for All-Cause Mortality, CHD, Stroke, and HF
Kaplan-Meier event curves for all-cause mortality, coronary heart disease (CHD), stroke, and heart failure (HF) among chlorthalidone, amiodipine, and lisinopril participants with atrial fibrillation (AF) or atrial flutter (AFL) at trial entry (n = 334) compared with those without AF/AFL (n = 30,370). CI = confidence interval; MI = myocardial infarction; RR = relative risk (hazard ratio).

Figure 2 Kaplan-Meier Cumulative Event Curves for All-Cause Mortality
Kaplan-Meier cumulative event curves for all-cause mortality in chlorthalidone, amiodipine, and lisinopril participants with AF/AFL at trial entry or occurring during follow-up (n = 821) compared with mortality in those without AF/AFL (n = 27,247). In this time-dependent analysis, participants without AF/AFL at baseline remained in the AF/AFL absent risk group until new-onset AF/AFL was ascertained, at which time they were reclassified as AF/AFL present. Participants who died before a follow-up electrocardiogram could be obtained were classified as AF/AFL absent. Abbreviations as in Figure 1.
