Data are presented as mean ± SD and as effect sizes (95% CI) for traits following a normal distribution. Remaining traits are presented as median (inter-quartile range) and their effect sizes are presented as increase/decrease in percentage. Multiple regression analysis was used to test for difference between genotype groups. P-values are corrected for sex and age. * = log transformation.
