Figure 2 Mean LVESVI, LVEDVI, and LVEF at Baseline and 12 Months in the CRT-OFF and CRT-ON Groups

Error bars represent 95% confidence intervals. Red circles = CRT-OFF (n = 163); green triangles = CRT-ON (n = 324). CRT = cardiac resynchronization therapy; LVEDVI = left ventricular end-diastolic volume index; LVEF = left ventricular ejection fraction; LVESVI = left ventricular end-systolic volume index; other abbreviations as in Figure 1.
