aValues are presented as means ± SD. bValues are presented as mean (with 95% confidence intervals) as appropriate. cAHI = apnea-hypopnea index. dBMI = body mass index. eODI = oxygen desaturation index. The age and BHI and AHI indexes were compared by independent-samples t-test, and the sex index was compared by the chi-square test; the other indexes of mean SaO2, minimum SaO2, and ODI indexes were compared by the Wilcoxon rank-sum test, respectively, using SPSS software.
