| Polyphenol Variables | Beta Estimate (SE) | p-Value | Beta Estimate (SE) | p-Value |
| Log total dietary polyphenols (mg/d) | 8.33 (12.90) | 0.5191 | 12.79 (18.95) | 0.5002 |
| Log total flavonoids (mg/d) | −14.27 (6.61) | 0.0316 | −17.23 (9.76) | 0.0785 |
| Log flavanols) (mg/d) | 4.70 (5.35) | 0.3801 | −0.29 (8.09) | 0.9717 |
| Log phenolic acids (mg/d) | −3.24 (7.00) | 0.6441 | −0.16 (10.31) | 0.9874 |
1 A linear regression model was fitted for each combination of urine polyphenol (dependent variable) and log dietary polyphenol (independent variable) while adjusting for age, gender, BMI. 2 Abbreviations: GAE = gallic acid equivalents, Cr = creatinine. p < 0.05 indicates significance.
