Equivalence in 6-month apnea-hypopnea indices (AHI) and change in AHI from baseline between randomization groups.

End point	tPSG	eHST	Estimate	95% CI	Equivalence Margin
6-month AHI	13.49 [7.75, 19.23], n = 19	14.62 [8.41, 20.83], n = 22	−0.23	−6.2, 4.2	−15, 15
6-month change in AHI	−21.89 [−28.33, −15.45], n = 19	−21.89 [−29.75, −14.03], n = 22	−0.01	−8.75, 8.74	−15, 15

Data presented as mean [95% CI]. For 6-month AHI, the estimate (median of differences or location shift) and confidence interval were derived using nonparametric Hodges–Lehmann test and for the change in AHI, the estimate (mean difference) and confidence interval were derived using the 2 1-sided tests procedure for independent t tests. CI = confidence interval, eHST = efficacy home sleep apnea test, tPSG = in-laboratory titration polysomnography.
