  • *Linear trend was tested using the quartiles of ELF score, TIMP1, PIIINP and HA as continuous variables.

  • †ELF score=2.278+0.851×ln(HA concentration)+0.751× ln(PIIINP concentration)+0.394×ln(TIMP1 concentration).

  • ‡Model 1: adjusted for age at blood-taking (years), education level (primary school and below, secondary or above) and fasting status (yes, no).

  • §Model 2: model 1 plus smoking (never, ever smoker), alcohol intake (never, ever drinker), weekly activity (<0.5, ≥0.5 hours/week), history of hypertension (yes, no) and body mass index (kg/m2).

  • ¶Model 3: model 2 plus triglycerides, high-density lipoprotein cholesterol, high-sensitivity C reactive protein, adiponectin, gamma-glutamyl transferase and alanine aminotransferase (all in quartiles).

  • ELF, enhanced liver fibrosis; HA, hyaluronic acid; PIIINP, amino-terminal propeptide of type III procollagen; Q, quartile; TIMP1, tissue inhibitor of matrix metalloproteinase 1.
