Independent Predictors of Major Events During Follow‐up in Cox Regression Analysis

	Hazard Ratio	P Value
Cause of death
Any cause, age >65 years	3.1 (95% CI: 1.1‐13.4)	0.047
Tp‐e/QT ratio ≥0.29	5.2 (95% CI: 1.9‐14.0)	<0.001
LVEF ≤0.45	2.7 (95% CI: 1.4‐6.3)
Cardiac cause of death
Age >65 years	2.1 (95% CI: 1.1‐3.3)	0.043
Tp‐e/QT ratio ≥0.29	7.2 (95% CI: 2.3‐22.9)	<0.001
LVEF ≤0.45	1.8 (95% CI: 1.2‐3.0)	0.005

Abbreviations: CI, confidence interval; LVEF, left ventricular ejection fraction; Tp‐e, interval from the peak to the end of the T wave.
