Estimates and 95% confidence intervals from a linear regression model examining the association between urine zinc (μg/dL) and zinc intake (mg).
| Nutrient | β | 95% CI | p-value |
|---|---|---|---|
| Zinc (mg) | 4.46 | 1.23–7.70 | 0.009 |
| Case:zinc intake | −3.58 | −7.47–0.30 | 0.08 |
| Phytate (mg) | −0.01 | −0.05–0.02 | 0.49 |
| Calcium (mg) | 0.003 | −0.03–0.02 | 0.82 |
Models included all three dietary recalls for each subject and were adjusted for dietary phytate and calcium and urine creatinine (mg/dL).
