80 patient RCT with 40 patients treated with a comprehensive regimen of nutritional support, showing significantly lower mortality with treatment. Treatment contained cholecalciferol, vitamin C, zinc, spirulina maxima, folic acid, glutamine, vegetable protein, selenium, resveratrol, omega-3 fatty acids, l-arginine, magnesium, probiotics, and B-complex IV. Adherence was strictly monitored. NCT04507867 (history).
risk of death, 85.7% lower, RR 0.14, p = 0.03, treatment 1 of 40 (2.5%), control 7 of 40 (17.5%), NNT 6.7.
risk of mechanical ventilation, 57.1% lower, RR 0.43, p = 0.31, treatment 3 of 40 (7.5%), control 7 of 40 (17.5%), NNT 10.0.
