Risk^* of All-Cause Mortality with Sleep-Disordered Breathing Among Participants Free of Diagnosed Stroke and Cardiovascular Disease at Baseline (n = 1471)^**

Baseline AHI category	Hazard Ratio (95% CI)
None: 0 – < 5	Reference
Mild: 5 – < 15	1.5 (0.8, 2.8)
Moderate: 15 – < 30	1.3 (0.5, 3.5)
Severe: ≥ 30	3.2 (1.4, 7.1)
	P trend = 0.01

^*Hazard ratios adjusted for age, age², sex, body mass index, and body mass index²

^**Participants with self-reported diagnosis of stroke (n = 8) and CVD (n = 43) excluded from sample

AHI denotes number of apnea and hypopnea events per hour of sleep, CI denotes confidence interval
