¹TDPs from 24-HRs or FFQs for uncorrected, deattenuated unadjusted, and adjusted deattenuated correlations were energy adjusted. *P < 0.001 (2-tailed). FFQ, food-frequency questionnaire; GAE, gallic acid equivalents; TDP, total dietary polyphenol; TUP, total urinary polyphenol; 24-HR, 24-h dietary recall.

²Transformed by using natural log + 1.

³Adjusted for age, race, sex, and BMI. For race-specific analysis, race was removed from the model.

⁴Corrected for attenuation due to within-person error in the recalls. Bias-corrected and accelerated bootstrap CIs were based on 2000 resampling.
