Computed tomography-based correction of the body mass index improves malnutrition detection in patients with cirrhosis and ascites

Global Leadership Initiative on Malnutrition (GLIM) reclassification was defined as patients who were not classified as having GLIM-defined malnutrition using the actual body mass index but were reclassified as having GLIM-defined malnutrition using the computed tomography-sensitive corrected body mass index. Continuous variables were compared using the Mann-Whitney U test, and categorical variables were compared using Fisher’s exact test. Patients lost to follow-up were excluded from the one-year mortality analysis.
