Summary of COVID-19 resveratrol studies
1. McCreary et al., Randomized double-blind placebo-controlled proof-of-concept trial of resveratrol for outpatient treatment of mild coronavirus disease (COVID-19)
100 patient resveratrol early treatment RCT: 67% lower hospitalization (p=0.62) and 43% lower progression (p=0.52).RCT 100 outpatients in the USA, showing lower hospitalization and progression with resveratrol, without statistical significance.

2. Mittra et al., Resveratrol and Copper for treatment of severe COVID-19: an observational study (RESCU 002)
230 patient resveratrol late treatment study: 44% lower mortality (p=0.06).Retrospective 230 severe COVID-19 patients in India, showing lower mortality with resveratrol + copper, without statistical significance. This study followed preclinical data showing that sepsis-related cytokine storm and fatality in mice could be prevented with oral administration of resveratrol and copper.

3. Kaplan et al., Reszinate—A Phase 1/2 Randomized Clinical Trial of Zinc and Resveratrol Utilizing Home Patient-Obtained Nasal and Saliva Viral Sampling
30 patient resveratrol late treatment RCT: 14% higher ventilation (p=1), 14% higher ICU admission (p=1), and 14% higher hospitalization (p=1).Small RCT of zinc plus resveratrol in COVID-19+ outpatients, showing no significant differences in viral clearance or symptoms. Although the treatment group was older (46.3 vs. 38.5) and had more severe baseline symptoms, they had similar symptomatic recovery by the second week. The SSRN manuscript ID is "EBIOM-D-21-03006," which is EBioMedicine's submission numbering format, suggesting that the paper may have been rejected by EBioMedicine and published elswhere. The treatment group had a much wider age range (20-73) compared to the placebo group (18-55), leading to a significant difference in variance (Levene's test p=0.002). While acknowledged by the authors, this baseline asymmetry suggests randomization did not fully balance the groups in this small cohort. Although the authors performed a post-hoc adjustment for age, the imbalance in a very small sample size limits the robustness of the findings.
