Determination of the cut-off score of an endoscopic scoring method to predict whether elderly patients with dysphagia can eat pureed diets

Figure 1 Endoscopic images of Hyodo-Komagane score. Salivary pooling in vallecula and piriform sinuses. A: A-0 no pooling; B: A-1 pooling at the only vallecula; C: A-2 pooling in vallecula and piriform sinuses and no penetration into larynx; D: A-3 pooling in vallecula and piriform sinuses and penetration into larynx.
