Notes: All continuous/numeric data have non-parametric distributions (Shapiro–Wilk’s p>0.05), are presented as median and interquartile range and were compared using Kruskal–Wallis’ test followed by Dwass-Steel-Critchlow-Fligner pairwise comparison. Categorical data are presented as counts and percentage and were compared with X2 test. Pos-hoc coding: a=no/mild OSA; b=moderate OSA, and c=severe OSA.
Abbreviations: AHI, apnea-hypopnea index; OSA, obstructive sleep apnea; RDI, respiratory disorder index; SpO2, percutaneous oxygen saturation; SpO2<90%, percentage of SpO2<90% out of the total sleep time.
