Association between Friedman score and AHI improvement evaluated by logistic regression analysis, n = 77.

		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	59 (76.6)	0.99 (0.61–1.60)	1.05 (0.62–1.76)	1.05 (0.62–1.76)

AHI: apnea-hypopnea index. OR: odds ratio, CI: confidence interval. N (%): AHI <10 or 15 and reduced >50%. Model 1: adjusted for age, sex, body mass index at inclusion, education level, and smoking. Model 2: adjusted for tonsil size + model 1.
