Fig. 3From: Prognostic impact of the prognostic nutritional index in cases of resected oral squamous cell carcinoma: a retrospective studyKaplan–Meier survival curves for the PNI and overall survival of oral squamous cell carcinoma patients. Kaplan–Meier curves, according to the PNI score. The OS was significantly worse in patients with a lower PNI than those with a higher PNI (≥ 42.9) (P = 0.0007886, respectively).
