(A) ROC curve of MMSE score for developing aspiration pneumonia in supratentorial stroke patients with dysphagia. The optimal cut-off value (dots on the curves) for MMSE score, which was obtained from the maximal Youden's index, was 18 or less for development of aspiration pneumonia (AUC, 0.707; 95% confidential interval, 0.600–0.800; P = .0023; sensitivity 93.75%, specificity 47.89%). (B) ROC curve of total modified Bathel index (MBI) score for developing aspiration pneumonia in infratentorial stroke patients with dysphagia. The optimal cut-off value (dots on the curves) for total MBI score, which was obtained from the maximal Youden's index, was 52 or less for development of aspiration pneumonia (AUC, 0.731; 95% confidential interval, 0.531–0.880; P = .0243; sensitivity 76.92%, specificity 73.33%). AUC = area under the ROC curve, MBI = modified Barthel index, MMSE = Mini-Mental State Examination, ROC = receiver operating characteristic.
