Figure 2

Four Kaplan–Meier curves for response category, LVEDD, QRS duration, and combination of LVEDD and QRS duration of cumulative incidence of composite endpoint at 4 years. (a) For composite endpoint, responders (red line) performed better compared to nonresponders (blue line). (b) For composite endpoint, LVEDD ≤ 69 mm group (red line) performed better compared to LVEDD > 69 mm group (blue line). (c) For composite endpoint, there was no difference between QRS duration ≤ 166 ms group and QRS duration > 166 ms group. (d) For composite endpoint, combination of QRS duration ≥ 170 ms and LVEDD ≤ 71 mm group (blue line) performed the best compared with others. HF: heart failure; LVEDD: left ventricular end-diastolic dimension.
