Fig. 1From: Prognostic impact of the prognostic nutritional index in cases of resected oral squamous cell carcinoma: a retrospective studyROC curve for the PNI. The continuous variables PNI and OS were used as the test and state variables, respectively. The PNI cut-off value was 42.9 with the area under the curve, sensitivity, and specificity being 0.634, 0.765, and 0.524, respectively.
