343.5 ng/mL, cut‐off of serum insulin‐like growth factor binding protein 2 levels for Patient‐Generated Subjective Global Assessment; Ab, abnormal; CRP, C‐reactive protein; IGFBP2, insulin‐like growth factor binding protein 2; N, normal; PDAC, pancreatic ductal adenocarcinoma.

P values were obtained by the Spearman rank correlation test.

^** p < 0.01.

^*** p < 0.001.
