Fig. 1 Kaplan-Meier actuarial survival curves for overall freedom from death and freedom from sudden cardiac death. Time 0 is the time of operation. The Annals of Thoracic Surgery 1997 64, 1713-1717DOI: (10.1016/S0003-4975(97)00922-3)
Fig. 2 Kaplan-Meier actuarial survival curves as stratified by older and younger age groups. No difference was noted by log-rank test. The Annals of Thoracic Surgery 1997 64, 1713-1717DOI: (10.1016/S0003-4975(97)00922-3)
Fig. 3 Kaplan-Meier actuarial survival curves as stratified by left ventricular function. The difference was statistically significant by the log-rank test. (LVEF = left ventricular ejection fraction.) The Annals of Thoracic Surgery 1997 64, 1713-1717DOI: (10.1016/S0003-4975(97)00922-3)
