  1. S.E. Standard Error; Good CPAP adherence, using CPAP for more than 4 h ≥ 70% of the 30 days prior to all follow-up points. Model was adjusting for age, sex, alcohol consumption, smoking, medication history of hypertension, medication history of diabetes, medication history of dyslipidemia, baseline body weight, and baseline Epworth Sleepiness Scale.
