  1. aMedian 8-hydroxydeoxyguanosine (8-OHdG) values were compared between age (<50, 50–59, ≥60 years), body mass index (BMI) (<18.5, 18.5–24.9, ≥25 kg/m2), and alcohol consumption (alcohol consumption, no alcohol consumption, previous alcohol consumption) groups using Kruskal–Wallis tests
  2. bMedian 8-OHdG values were compared between the smoking status (smoker and non-smoker) groups using Mann–Whitney tests
