Data are unadjusted β coefficients (95% CIs). Model 1, unadjusted; model 2, adjusted for age, sex, and BMI; model 3, adjusted as for model 2 plus liver-spleen ratio, a measure of liver fat content. *Statistically significant association, P < 0.05. FFA, free fatty acid; PL, phospholipid.
n = 32 for PL analyses and n = 30 for FFA analyses.
