Prevalence, characteristics, and respiratory arousal threshold of positional obstructive sleep apnea in China: a large scale study from Shanghai Sleep Health Study cohort

Table 3 Adjusted ORs and 95% CIs for the Association between POSA and ArTH according to CC and APOC

Model 1 was adjusted for age, BMI, and sex. Model 2 was adjusted for variables included in Model 1 and NC, WC, HC, alcohol consumption, smoking. Model 3 was adjusted for variables included in Model 2 and TST, ESS, MAI, CT90. OR odds ratio, CI confidence interval, POSA positional obstructive sleep apnea; ArTH, respiratory arousal threshold; CC, Cartwright Classification; APOC Amsterdam Positional Obstructive Sleep Apnea Classification; CC-NPOSA non-positional obstructive sleep apnea according to Cartwright Classification, Si-POSA supine-isolated positional obstructive sleep apnea; Sp-POSA, supine-predominant positional obstructive sleep apnea; APOC-NPOSA, non-positional obstructive sleep apnea according to Amsterdam Positional Obstructive Sleep Apnea Classification, BMI body mass index; NC neck circumference, WC waist circumference; HC, hip circumference; TST, total sleep time, ESS Epworth Sleepiness Scale, MAI micro-arousal index, CT90 the cumulative time spent at oxygen saturation below 90% in total sleep time. ** indicated p-value < 0.05 and *** indicated p-value < 0.001 for the logistic regression. NPOSA group was the reference category in each subgroup analysis
