  1. Values were expressed as odds ratio (OR) and 95% confidence interval (CI). Factors associated with smoking cessation were determined by univariate and multivariate logistic regression analysis. Multivariate analysis was adjusted for age, sex, disease duration, occupation, BMI, pack-years and years of smoking. AHI, apnea and hypopnea index; BMI, body mass index; MSaO2, mean oxygen saturation during sleep; ODI, oxygen desaturation index; OSA, obstructive sleep apnea.
