	HR (95% CI)	P Value	C‐index (95% CI)
ECG‐LVH	1.32 (1.03‐1.69)	0.026	0.772 (0.726‐0.815)
Echo‐LVH	1.49 (1.21‐1.85)	0.0002	0.772 (0.727‐0.815)

Abbreviations: BMI, body mass index; CHD, coronary heart disease; CI, confidence interval; DM, diabetes mellitus; ECG‐LVH, electrocardiographic left ventricular hypertrophy; echo‐LVH, echocardiographic left ventricular hypertrophy; HF, heart failure; HR, hazard ratio; SBP, systolic blood pressure.
