§N=209. Five participants had insufficient amount of blood for HbA1c measurements. The mean age of these was 32 years and the s-25(OH)D was 36.4 nmol/L (16.7), three persons were in the 10 µg group while the others were in the two other groups each.
BMI, body mass index; HbA1c, glycated hemoglobin; HDL, high-density lipoprotein; LDL, low-density lipoprotein; S-25(OH)D, serum 25-hydroxyvitamin D.
