Relationship between chronological age (CA) and 8-oxo-7,8-dihydroguanosine (8-OHdG). 8-OHdG concentrations are normalized to urinary creatinine content, and their natural logarithmic values are shown (measurement unit: μg/g). Ln(8-OHdG) significantly correlated with CA in females (, ) but neither in males (, ) (a); nor ex-smokers (, ), nor never-smokers (, ) (b).
