In our study, the malnutrition scoring systems, CONUT, GNRI, and PNI, consisted of some inflammatory markers (serum albumin and lymphocyte count) and nutritional markers (total cholesterol, BMI), and were associated with inflammatory biomarkers and systemic inflammation score, suggesting that malnutrition may reflect high inflammatory and metabolic status, which contributes to the development of SAP. Here, ALB is linked to malnutrition.
