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

Table 5 Comparison of the clinical characteristics between patients with and without Global Leadership Initiative on Malnutrition-defined malnutrition reclassification (actual body weight method vs computed tomography -sensitive corrected method), n (%)/median (Q1, Q3)

Variable	No reclassification (n = 95)	Reclassification (n = 5)	P value

Actual BMI, kg/m2	24.34 (22.56, 26.32)	20.03 (19.03, 20.90)	0.006
CT-corrected BMI, kg/m2	23.70 (21.57, 25.51)	17.74 (17.49, 19.27)	0.001
CT-sensitive corrected BMI, kg/m2	23.65 (21.44, 25.51)	17.74 (17.49, 18.16)	0.001
AMC, cm	23.54 (22.54, 24.23)	21.42 (21.01, 21.82)	0.084
Albumin, g/L	33.20 (27.80, 38.70)	36.50 (32.00, 38.30)	0.840

INR	1.22 (1.10, 1.41)	1.46 (1.17, 1.75)	0.174
Ascites volume, mL	1438.40 (617.12, 2324.45)	6003.70 (4500.38, 6348.66)	0.001
Severe lower-limb edema	6 (6.3)	3 (60.0)	0.005

Continuous variables are presented as the median (Q1, Q3) and were compared using the Wilcoxon rank-sum test. Categorical variables are presented as counts or percentages and were compared using Fisher’s exact test. CT: Computed tomography; BMI: Body mass index; INR: International normalized ratio; AMC: Arm muscle circumference.
