OR, odds ratio; CI, confidence intervals; OBS, oxidative balance score
Dietary OBS: Q1: 0 ≤ Dietary OBS<10; Q2: 10 ≤ Dietary OBS<16; Q3: 16 ≤ Dietary OBS<22; Q4: Dietary OBS ≥ 22.
Life OBS: Q1: 0 ≤ Life OBS<3; Q2: 3 ≤ Life OBS<4; Q3: 4 ≤ Life OBS<6; Q4: Life OBS ≥ 6.
The model 1 was the crude model
The model 2 was adjusted by age, gender, race, poverty-to-income ratio, energy intake, caffeine intake, protein intake and sugar intake
The model 3 was adjusted by age, gender, race/ethnicity, poverty-to-income ratio, CKD, diabetes, hypertension, hyperlipidemia, CVD, energy intake, caffeine intake, protein intake and sugar intake
