Association between Friedman score and treatment compliance evaluated by logistic regression analysis, stratified by treatment group, CPAP n = 55, MAS n = 48.

		Treatment compliance (>4 hours, >70% nights)
	n (%)	Crude OR (95% CI)	Model 1 OR (95% CI)	Model 2 OR (95% CI)
1-point increase in Friedman score, CPAP	18 (32.7)	0.89 (0.53–1.47)	0.96 (0.57–1.62)	0.90 (0.53–1.54)
1-point increase in Friedman score, MAS	36 (75.5)	0.68 (0.35–1.30)	1.03 (0.42–2.52)	0.98 (0.39–2.48)

CPAP: continuous positive airway pressure; MAS: mandibular advancement splint; OR: odds ratio, CI: confidence interval. N (%): using CPAP/MAS >4 hours, >70% of nights. Model 1: adjusted for age, sex, body mass index at inclusion, education level, and smoking. Model 2: adjusted for tonsil size + model 1.
