HRs (95% CI) for incident diabetes in participants in the highest magnesium intake quintile compared with those in the lowest quintile, stratified by sex, ethnicity, family history of diabetes, and BMI. Data in the parentheses in the group column are the ratio of the number of events to number of participants. The adjusted covariates in the models were the same as those for model 3 in Table 2. *Continuous variables using the median value in each quintile were created for trend tests.
