  1. ISSCC Imaging subcohort of South China Cohort, MAFLD metabolic dysfunction-associated fatty liver disease, MASH metabolic dysfunction-associated steatohepatitis, NHANES National Health and Nutrition Examination Survey, SF significant fibrosis.
  2. In Imaging subcohort of South China Cohort, values were presented as means ± SD or numbers (percentages). P values were calculated using analysis of variance and χ2 test for continuous and categorical variables, respectively. In US NHANES, all estimates accounted for complex survey designs and presented as weighted means (SE) or numbers (weighted percentages). P values were calculated using analysis of variance adjusting for sampling weights and Rao-Scott χ2 test for continuous and categorical variables, respectively.
