Bold means statistically significant (P < 0.05).

Adjustment 1: Multivariate analysis controlling for height, age, sex, and ethnicity; Adjustment 2: Multivariate analysis controlling for height, age, sex, ethnicity, and subtotal fat mass; Adjustment 3: Multivariate analysis controlling for height, age, sex, ethnicity, and weight.

The regression estimate (ß) demonstrates how a 1-U change in each of the body indices affects PDFF on a logarithmic scale.
