Data are shown in mean ±SD for continuous variables and percentages for categorical. P-value by independentt-test for continuous and by Chi-Square for categorical variables. AHI= apnea hypopnea index; BMI= body mass index; eGFR= estimated glomerular filtration rate indexing per 1.73m2 for body surface area.
