RR, relative risk; CI, confidence interval. The reference category is based on the lowest category of intake. Diet was assessed in 1993 and adult-onset between 1993 and 2003.

^*Based on each intake category and modelling these as continuous variables in a Cox model.

^†Cox models adjusted for caloric intake, body mass index, tobacco consumption, physical activity, menopausal status, education and multivitamin supplements use.
