FIGURE 2.

Adjusted systolic and diastolic blood pressure (BP) across chronotype groups in participants with an apnea–hypopnea index (AHI) < 15 and an AHI ≥ 15 events per hr. (a, b) Systolic and diastolic BP, respectively. Error bars reflect 95% confidence interval (CI) of standard error of the mean. Variables assessed as potential covariates for models were age, sex, body mass index (BMI; kg m⁻²), alcohol, smoking, physical activity, self‐reported sleep duration, depressive symptoms, insomnia symptoms, AHI, and anti‐hypertensive medication. Covariates were excluded if p‐value > 0.05 or multicollinearity existed
