Fig. 3: Association between obstructive sleep apnea (OSA) severity with uncontrolled hypertension.
From: High night-to-night variability in sleep apnea severity is associated with uncontrolled hypertension

Odds ratio (Estimate and 95% confidence interval) of the association between obstructive sleep apnea (OSA) severity with hypertension. This model is controlled for age, sex, and BMI. OSA category was defined using standard clinical cut-offs of the apnea–hypopnoea index where <5 = no OSA, ≥5 and <15 = mild, ≥15 and <30 = moderate and ≥30 events/h sleep = severe OSA).
