Urinary Biomarkers of Oxidative Stress in Aging: Implications for Prediction of Accelerated Biological Age in Prospective Cohort Studies
Figure 3
Relationship between chronological age (CA) and dityrosine (DTyr). DTyr concentrations are normalized to urinary creatinine content and their natural logarithmic values are shown (measurement unit: μg/g). (a) Ln(DTyr) significantly correlated with CA both in females (, ) and in males (, ). (b) Ln(DTyr) significantly correlated with CA both in nonsmokers (, ) and in ex-smokers (, ).
