Also, in the active group (n = 79) GPx3 was associated with renal function (CKD-EPI CysC: r = 0.26, p = 0.022; CKD-EPI creat: r = 0.26, p = 0.019; CKD-EPI creat/CysC: r = 0.27, p < 0.016), while no significant correlations were found between GPx3 and parameters of renal function in the placebo group. Here, GPX3 is linked to chronic kidney disease.
