When stratifying by groups, T50 was significantly correlated to serum zinc levels in CKD patients (Spearman r 0.2469, P = .001, n = 193), but this correlation did not reach statistical significance in blood donors (Spearman r 0.1541, P = .094, n = 119) or dialysis patients alone (Spearman r 0.1018, P = .199, n = 161).
