Friedman Score in Relation to Compliance and Treatment Response in Nonsevere Obstructive Sleep Apnea

Table 5

Association between Friedman score and AHI improvement evaluated by logistic regression analysis, stratified by treatment group, CPAP n = 38, MAS n = 39.

		AHI <10 or AHI <15 and reduced>50% at final follow-up
	n (%)	Crude; OR (95% CI)	Model 1; OR (95% CI)	Model 2; OR (95% CI)
1-point increase in Friedman score, CPAP	38 (100)	N.A.	N.A.	N.A.
1-point increase in Friedman score, MAS	21 (53.8)	1.01 (0.56–1.81)	1.02 (0.53–1.98)	1.02 (0.53–1.98)

CPAP: continuous positive airway pressure; MAS: mandibular advancement splint; AHI: apnea-hypopnea index. OR: odds ratio, CI: confidence interval n (%): AHI <10 or 15 and reduced >50%. N.A.: all patients achieved AHI <10 at follow-up. Model 1: adjusted for age, sex, body mass index at inclusion, education level, and smoking. Model 2: adjusted for tonsil size + model 1.
