Figure 2: Graphical representation of sonographic predicted HMDR, Pre E/E-VC (mean ± SD) to Cormack–Lehane Grading. HMDR: Hyomental distance ratio. Pre E/E-VC: Ratio of depth of preepiglottic space to the distance between epiglottis and midpoint of vocal cord, *P = 0.00; P > 0.05 (HMDR between Cormack–Lehane 1 and Cormack–Lehane 2)
