After 2 weeks, the remaining 5 patients in the quercetin group tested negative for SARS-CoV-2, then while in the standard care group, of the remaining 19 patients, 17 showed a negative result at week 2, one negative result at week 3, and one patient, still positive, died at day 20. On the background of quercetin therapy, LDH, and ferritin levels decreased, CRP and D-dimer. | [140] |
