The area under the ROC curves (AUC) for DSHB, DSEM, DSAC, MMS, IIG, and TMD.

Parameters	AUC ±SE	95% CI	P
DSHB	0.92±0.03	0.87 to 0.95	<0.0001
DSEM	0.90±0.03	0.85 to 0.94	<0.0001
DSAC	0.85±0.04	0.79 to 0.89	<0.0001
MMS	0.71±0.05	0.64 to 0.77	<0.0001
IIG	0.58±0.06	0.51 to 0.65	0.17
TMD	0.51±0.07	0.44 to 0.58	0.89

AUC ±SE – area under the ROC curves ± Standard Error; 95% CI – 95% Confidence Interval; DSHB – distance between skin and hyoid bone; DSEM – distance between skin and epiglottis; DSAC – distance between skin and anterior commissure; MMS – Modified Mallampati Score; IIG – inter incisor gap; TMD – thyromental distance.
