Risk factor	Sudden cardiac death, 72 events		Coronary Heart Disease Death, 102 events
	Hazard ratio (95% CI)	P-value	Hazard ratio (95% CI)	P-value
Asymptomatic ST-depression during exercisea	2.13 (1.15–3.89)	0.015	2.47 (1.52–3.99)	<0.001
Asymptomatic ST-depression during recoverya	3.17 (1.68–5.96)	<0.001	4.01 (2.12–7.58)	<0.001
