Model 1: unadjusted model.

Model 2: adjusted for age, gender and amylase.

Model 3: NLR was adjusted for age, gender, amylase, CRP, RDW, PNI and LMR; CRP was adjusted for age, gender, amylase, NLR, RDW, PNI and LMR; RDW was adjusted for age, gender, amylase, CRP, NLR, PNI and LMR; PNI was adjusted for age, gender, amylase, NLR, CRP, RDW and LMR; LMR was adjusted for age, gender, amylase, NLR, CRP, RDW and PNI.

AP, acute pancreatitis; CRP, C reactive protein; LMR, lymphocyte–monocyte ratio; NLR, neutrophil–lymphocyte ratio; PNI, prognostic nutritional index; RDW, red cell distribution width; SAP, severe acute pancreatitis.
