|---|---|---|---|---|---|---|
| Type of Copper | HR | 95% CI | HR | 95% CI | HR | 95% CI |
| Total copper | 1.17 | 0.89, 1.45 | 1.50 | 1.00, 2.00 | 1.05 | 0.78, 1.33 |
| Copper from food | 1.20 | 0.92, 1.48 | 1.49 | 1.04, 1.95 | 1.08 | 0.81, 1.36 |
| Copper from supplements | 0.98 | 0.91, 1.04 | 1.01 | 0.85, 1.16 | 0.97 | 0.90, 1.05 |
Abbreviations: CI, confidence interval; HR, hazard ratio.
a Models adjusted for age, sex, race-center, apolipoprotein E ε4 allele, education, body mass index, smoking, alcohol consumption, total calorie intake, saturated fat intake, zinc intake, iron intake, and dietary patterns. P for interaction between copper from food and high saturated fat is 0.03; P for interaction between copper from supplements and high saturated fat is 0.68; and P for interaction between total copper and high saturated fat is 0.03.
