Table 1 Comparison of the study population to the background population.

	Study population	Inter99 background population	p-value
Sex (males/females)	181 (43.0)/240 (57.0)	3121 (49.0)/3242 (51.0)	0.02*
Age (years)	46.6 (8.1)	46.0 (8.0)	0.14
IHD risk (%)	4.5 (1.0–65.8)	4.8 (0.4–77.0)	0.53§
Fasting p-glucose (mmol/l)	5.4 (3.0–19.7)	5.4 (2.0–23.9)	0.23§
120-min p-glucose (mmol/l)	5.9 (2.5–25.9)	5.9 (1.4–30.6)	0.90§

Ischemic heart disease (IHD) risk was calculated as the risk of having an IHD event projected to occur between the age of 60 and 70 years using the Precard ^® software. [21] Data are shown in mean (SD) for age and median (range) for IHD risk, fasting p-glucose, and 120-min post OGTT p-glucose, or actual numbers (%) for sex. P-values were calculated using the Students t-test when data were normally distributed or the non-parametric equivalent, the Mann-Whitney U-test (§) when data were not normally distributed. * A χ²-test was used.
