Fig. 2From: The role of prognostic nutritional index in the management of pulmonary sarcomatoid carcinomaKaplan–Meier survival curves evaluate the recurrence-free survival (RFS) in patients with completely resected PSC (n = 91) stratified according to prognostic nutritional index (PNI). RFS rate was significantly worse for patients with PNI less than 49.4 than for patients with PNI equals or higher than 49.4 (P < 0.001)Back to article page
