Variables	PS	OSA	p	95%CI
Hys	86.4 ± 1.3	88.5 ± 0.9	0.18	−1.05;5.25
HyMP	10.9 ± 0.9	13.1 ± 0.5	0.03a	0.08;4.32

95% CI, 95% confidence interval; PS, primary snoring; OSA, obstructive sleep apnea; HYS, distance between the hyoid and the base of the skull; HYMP, distance between the hyoid and the mandibular plane (Go-Me); horiz.d-H, measure between the Hy (hyoid) point and the posterior pharyngeal wall; vert.d-H, distance from the Hy point (hyoid) to the palatal plane (ENA-ENP); C3-H, measure from Hy point (hyoid) to C3 point (cervical column).
