CI, confidence interval; OR, odds ratio; VAT, visceral adipose tissue area on bioelectrical impedance assay.

a

Model 1: Adjusted for sex, age, diagnosis, forced vital capacity.

b

Model 2: Adjusted for Model 1 covariates + body mass index.

c

Model 3: Adjusted for Model 2 covariates + skeletal muscle mass.
