Fig. 1From: The prognostic value of Tiam1 protein expression in head and neck squamous cell carcinoma: a retrospective studySelection of the cut-off score for T lymphoma invasion and metastasis 1 (Tiam1) expression by the receiver operating characteristic (ROC) analysis. The area under the curve (AUC) is 0.692. An expression score of 5 maximizes the Youden Index [sensitivity (0.802) + specificity (0.584) − 1 = 0.386]Back to article page
