Patients with the FOXO3 rs4946936 T allele were less likely to be diagnosed with dyslipidemia according to the K/DOQI criteria (OR 0.686, 95% CI 0.517–0.910, p = 0.009) and had lower serum concentrations of total cholesterol and LDL-cholesterol than the bearers of the CC genotype (p = 0.029 and 0.036, respectively) (Table S6). Here, FOXO3 is linked to metabolic syndrome.
