Table 2.

Multivariable adjusted hazard ratio and 95% confidence intervals of incident hypertension in mild and moderate OSA

Predictors	N	HR (95% CI)
Controls	641	Reference
Mild-to-moderate OSA	103	2.94 (1.96–4.41)
Controls	641	Reference
Mild OSA	71	3.24 (2.08–5.03)
Moderate OSA	32	2.23 (1.10–4.50)

All data present were adjusted for sampling weight, sex, race, baseline age, BMI, smoking, diabetes, mean arterial pressure and treatment for OSA. Controls were defined as AHI < 5 events/hour, Mild-to-moderate OSA was defined as AHI 5–29.9 events/hour, Mild OSA was defined as AHI 5–14.9 events/hour and Moderate OSA was defined as AHI 15–29.9 events/hour.
