Characteristics of the study population with adjusted mean levels of HbA_1c at baseline (1994/95) and follow-up (2004/05).

BMI = body mass index, HbA1c = hemoglobin A1c, HDL = high density lipoprotein, SEM = standard error of the mean *age- and sex-adjusted mean HbA1c, for adjustment age was treated continuously, age was only sex adjusted, sex was only age adjusted **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.
