⁺The reference category is <=3mg/L

OR1 Adjusted for age, kcal/day, occupation, education, income, physical activity, CVD, and assay batch; In addition the smoking analysis was adjusted for alcohol and tea consumption, the alcohol analysis was adjusted for smoking and tea consumption, and the tea consumption analysis was adjusted for smoking and alcohol consumption.

OR2 As above plus BMI
