For categorical variables, 0 indicates “female or no” and 1 indicates “male or yes.” Only statistically significant variables () are shown. WC: waist circumference; MAI: microarousal index; AHI: apnea-hypopnea index; SIT90: saturation impair time below 90%; B: partial regression coefficient; SE: standard error; OR: odds ratio; CI: confidence interval.
