All measurements were described as mean ± SD. *Statistically significant at P ≤ .05. a2-month vs baseline within TSD users group. b2-month vs baseline within MAD users group. cΔTSD vs ΔMAD. dNonparametric test. BP = blood pressure, CI = confidence interval, MAD = mandibular advancement device, OA = oral appliance, SD = standard deviation, TSD = tongue-stabilizing device, Δ = 2-month variable − baseline variable.
