Association of Body Composition Z-Scores with Hepatic Steatosis by Multivariate Analysis
| Category | Measure | ß | R 2 | P |
|---|---|---|---|---|
| Absolute adipose mass | BMI z-score | 0.575 | 0.276 | <0.001 |
| Total body percent fat z-score | 0.466 | 0.210 | <0.001 | |
| Body fat distribution | Trunk/limb fat mass ratio z-score | 0.657 | 0.392 | <0.001 |
| Absolute lean mass | Appendicular lean mass/height2 z-score | 0.320 | 0.213 | <0.001 |
Bold means statistically significant (P < 0.05).
Multivariate analysis controlling for height, age, sex, and ethnicity. The regression estimate (ß) demonstrates how a 1-U change in each of the body indices affects PDFF on a logarithmic scale.
