Adjusted mean levels of HbA_1c by categories of exposure variables at baseline (1994/95) and follow-up (2004/05).

HbA1c = hemoglobin A1c, SEM = standard error of the mean *age- and sex-adjusted mean HbA1c, for adjustment age was treated continuously **p for adjusted mean difference (analysis of covariance); numbers of people in categories in column “n Total” do not sum up to the number in the total study population because of missing values and because subjects with intakes as needed are not listed. Adjusted mean levels of HbA1c by categories of exposure variables at baseline (1994/95) and follow-up (2004/05).
