All values are reported as Spearman correlation coefficient (P-value).
aSG-SG: Subglosso-supraglottis.
bMPH: Mandibular plane-hyoid distance.
cPatients might have more than or equal to one site of complete lateral wall collapse that collapsibility was more than 90%.
*Two-tailed P-values less than 0.05.
