Data are presented as n, unless otherwise stated. The reference category is based on the lowest category of intake. Diet was assessed in 1993 and current asthma was assessed in 2003.OR: odds ratio; CI: confidence interval. #: for trend. Based on each intake category and modelling these as continuous variables in a logistic regression. ¶: logistic regressions adjusted for age, caloric intake, body mass index (BMI), tobacco consumption, physical activity, menopausal status, education and multivitamin supplement use. +: logistic regressions adjusted for age, caloric intake, BMI, tobacco consumption, physical activity, education and menopausal status. n = 53,101.
