Group 1 = genotypes AA 1G/1G, AA 1G/2G, AG 1G/1G, AG 1G/2G

Group 2 = genotypes AA 2G/2G, AG 2G/2G

Group 3 = genotypes GG 1G/1G, GG 1G/2G

Group 4 = genotypes GG 2G/2G

SD = standard deviation of the mean

n = number of cases

BMI = Body mass index

n.s. = not significant

One-way ANOVA was used to test for significant differences
