Fig. 2. Hypopharyngeal impedance baseline values negatively correlated with Hyodo scores. The optimal cutoff value of the baseline impedance (BI) in Z1 (impedance channel positioned at hypopharynx) to identify the presence of swallowing dysfunction was determined to be 1552 Ω +. The corresponding sensitivity was 0.93, specificity was 0.50, and the area under the curve (AUC) was 0.74.
