CRP and Increased total leukocyte count: CRP/PNI ratio is correlated significantly with CRP (P <0.001), leukocytosis (P =0.003), lymphocyte counts (P <0.001), hypoalbuminemia (P =0.001), PNI (P <0.001) and survival (P <0.001), but no relationships were found between CRP/PNI ratio and other factors such as comorbidity, platelet count and anemia.
