COVID-19: Poor outcomes in patients with zinc deficiency

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, treatment 0 of 20 (0.0%), control 5 of 27 (18.5%), continuity correction due to zero event (with reciprocal of the contrasting arm).

risk of ICU admission, 92.4% lower, RR 0.08, p = 0.02, treatment 0 of 20 (0.0%), control 7 of 27 (25.9%), continuity correction due to zero event (with reciprocal of the contrasting arm).

Effect extraction follows pre-specified rules prioritizing more serious outcomes. For an individual study the most serious outcome may have a smaller number of events and lower statistical signficance, however this provides the strongest evidence for the most serious outcomes when combining the results of many trials.

Elimination of COVID-19 is a race against viral evolution. No treatment, vaccine, or intervention is 100% available and effective for all current and future variants. Denying the efficacy of any method increases the risk of COVID-19 becoming endemic; and increases mortality, morbidity, and collateral damage. We do not provide medical advice.
