Notes: data were presented as mean ± standard deviation or median (25th and 75th percentiles) according to distribution normality. Normally distributed parameters of three groups were compared using one‐way ANOVA test, whereas non‐normally distributed parameters were compared using Kruskal–Wallis test, with Bonferroni adjustment for post hoc analysis. ^aStatistical significance between groups A and C. ^bStatistical significance between groups B and C. ^CStatistical significance between groups A and B. AHI, apnea and hypopnea index; LSpO₂, lowest oxygen saturation; MAI, microarousal index; ODI, oxygen desaturation index; TST, total sleep time; SE, sleep efficiency; T<90%, percentage of total sleep time spent with oxyhemoglobin saturation below 90%.
