Figure 2.

Receiver operating characteristic curve, shows the area under curve for condylar mobility (green), age (blue), TT (yellow line) and reference line (violet). Difficult laryngoscopy was taken as Cormack-Lehane grade >2. Higher values of age and tongue thickness are represented on the left side of the curve, and lower values of condylar mobility are represented on the right side of the curve predicting difficult laryngoscopy
