Data are summarized as mean (standard deviation) or n (%) as appropriate. Abbreviations: AHI: apnea–hypopnea index; AI: apnea index; BMI: body mass index; nO-nS: non-obese with non-severe OSA; nO-S: non-obese with severe OSA; O-nS: obese with non-severe OSA; O-S: obese with severe OSA; OSA: obstructive sleep apnea; SpO2: oxygen saturation measured by pulse oximetry. 1 Data were compared using one-way analysis of variance with post-hoc Tukey’s honestly significant difference tests. 2 p-value < 0.05 when the variable in the nO-nS subgroup was compared with the nO-S, O-nS, or O-S subgroup. 3 p-value < 0.05 when the variable in the nO-S subgroup was compared with the O-nS or O-S subgroup. 4 p-value < 0.05 when the variable in the O-nS subgroup was compared with the O-S subgroup. Significant p-values are marked in bold. * p-value < 0.05 when variables were compared between baseline and post-AT data.
