In addition, the significance of the parameters was identified for END-1, END-2, TBARs (AUC 0.713; p = 0.004), AGEs (AUC 0.667; p = 0.011), SOD (AUC 0.747; p < 0.001), GSH/GSSG (AUC 0.652; p = 0.030), GPx (AUC 0.687; p = 0.004), GSTpi (AUC 0.796; p < 0.001), and GR (AUC 0.768; p < 0.001) for the group with COVID-19+ versus the control (Table 4, Figure 3). The gene discussed is SOD1; the disease is COVID-19.
