Association between PNI and plasma ghrelin levels or D/A, and between HS-mGPS) and total plasma ghrelin or D/A. (A) PNI and plasma ghrelin levels demonstrated a negative association. (B) Total ghrelin levels in patients with an HS-mGPS score of 1 were significantly lower than those patients with a score of 2. *P<0.05 as indicated. D/A, desacyl ghrelin-to-acyl ghrelin ratio; PNI, prognostic nutritional index; D/A, desacyl ghrelin-to-acyl ghrelin ratio; HS-mGPS, high-sensitivity modified Glasgow Prognostic Score; A, acyl; D, desacyl; T, total.
