Table 3.
Linear regression models to evaluate associations of lead dose biomarkers with uric acid levels (n = 803).
| Model | Lead variable | β-coefficient | SE β | p-Value | Model r2 |
|---|---|---|---|---|---|
| 1 | Tibia lead (μg Pb/g bone mineral) | −0.0005 | 0.0010 | 0.62 | 0.32 |
| 2 | Blood lead (μg/dL) | 0.0027 | 0.0027 | 0.32 | 0.31 |
| 3 | DMSA-chelatable lead (μg Pb/g creatinine) | 0.0259 | 0.0431 | 0.55 | 0.31 |
Uric acid was modeled separately as the outcome, with one of the three lead biomarkers included per model. Regression results from each model are presented only for the association of the lead biomarker with uric acid. Models were also adjusted for age, sex, BMI, and alcohol use.
