^aP < 0.05 indicates statistical significance after Bonferroni correction. A P value of < 0.05 is considered to show a trend.

According to normality distribution, continuous data is presented in mean (± SD) or median (interquartile range). Quantitative outcome variables were compared using the independent t-test and Mann-Whitney U test according to normality distribution. Fisher’s exact test was used to analyze categorical data. Definitions of collectively assessed cardiometabolic co-morbidity: Obesity is defined as body mass index > 25 or abnormal waist-to-hip ratio; metabolic dysfunction-associated steatotic liver disease; hypercholesterolemia as total cholesterol > 5 mmol/L or use of statins; hypertension is defined as measured systolic blood pressure of ≥ 135 mmHg and or a diastolic blood pressure ≥ 85 mmHg and or use of antihypertensive medication; type 2 diabetes (T2D) is defined as blood glucose > 11 mmol/L after a 2-hour oral glucose tolerance test, or hemoglobin A1c > 48 or use of antidiabetic medicine intended to treat T2D. ALT: Alanine aminotransferase; AUC: Area under the curve; BMI: Body mass index; CAP: Controlled attenuation parameter; FIB-4: Fibrosis index 4 factors; HbA1c: Hemoglobin A1c; HBeAg: Hepatitis B e antigen; HBV: Hepatitis B virus; HDL: High-density lipoprotein; Anti-HBc: Hepatitis B core antibodies; Anti-HBs: Hepatitis B surface antibodies; Anti-HDV: Hepatitis D virus antibodies; IQR: Interquartile range; LDL: Low-density lipoprotein; MASLD: Metabolic dysfunction-associated steatotic liver disease; TE: Transient elastography; WHR: Waist-to-hip ratio.
