Model 1 was adjusted for age (years) of patient and sex of patient, and alanine aminotransferase (U/L) and creatinine (µmol/L) levels, along with ^afat mass (kg), ^bmuscle mass (kg), and ^cmuscle mass/ht² (kg/m²)

Model 2 was adjusted for age (years) of patient, sex of patient, and hemoglobin A1c levels (%), along with ^afat mass (kg), ^bmuscle mass (kg), and ^cmuscle mass/ht² (kg/m²)

Model 3 was adjusted for age (years) of patient and sex of patient, and total cholesterol (mmol/L) and triglyceride levels (mmol/L), along with ^afat mass (kg), ^bmuscle mass (kg), and ^cmuscle mass/ht² (kg/m²)

OR, odds ratio; CI, confidence interval; BFMI, body fat mass index; SMI, skeletal muscle index; ht², height squared
