“…As can be seen in Table 4 , younger COVID-19 patients displayed tendencies of higher average GSH and GSSG values and showed higher average GSH:GSSG ratios compared to older COVID-19 subjects indicating a more reduced oxidative state [ 48 ]. Interestingly, the GSH:GSSG ratios of the older COVID-19 patients were also comparable to those of healthy older adults published in other studies [ 60 ]. Thus, we suggest that the acute COVID-19 infections did not adversely influence the redox state in the hospitalized patients [ 1 , 20 , 39 , 40 ].…”
