GPX1 and obesity disorder: In an additional analysis performed in children with normal weight and with obesity separately, the inverse relationship between sTAC and TBARS in non-recessive carriers (GG + GA) of SOD2 rs4880 (β = −4.564 ± 1.274, p < 0.001) and dominant carriers (GA + AA) of GPX1 (β = −4.961 ± 1.371, p < 0.001) remained significant only in children with obesity (Supplementary Table S6).
