Variables entered into the stepwise regression analyses were indicated in Table 2 by variables yielding P-value <0.10; only variables left in one or more of the models are shown in this table. Minus sign means the variable was not selected through univariate or stepwise selection procedures. CTLFA is negatively correlated with liver fat accumulation.
Abbreviations: CTLFA, CT values for liver; β = standard regression coefficient; R2 = coefficient of determination; BMI, body mass index; CRP, C-reactive protein.
