COVID-19: Poor outcomes in patients with zinc deficiency
(Peer Reviewed)
Prospective study of zinc levels in 47 hospitalized COVID-19 patients and 45 healthy controls. COVID-19 patients had significantly lower zinc levels (74.5 vs. 105.8 median μg/dl, p < 0.001). 57.4% of COVID-19 patients were zinc deficient, and they had higher rates of complications, ARDS, prolonged hospital stay, and increased mortality.

risk of death, 89.7% lower, RR 0.10, p = 0.06, high zinc levels 0 of 20 (0.0%), low zinc levels 5 of 27 (18.5%), NNT 5.4, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).

risk of ICU admission, 92.4% lower, RR 0.08, p = 0.02, high zinc levels 0 of 20 (0.0%), low zinc levels 7 of 27 (25.9%), NNT 3.9, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).
