Fromonot et al., 5/3/2021, prospective, France, Europe, peer-reviewed, 6 authors.
risk of hospitalization, 89.2% lower, RR 0.11, p = 0.002, high zinc levels 6 of 110 (5.5%), low zinc levels 7 of 42 (16.7%), odds ratio converted to relative risk, within COVID-19 patients.
risk of COVID-19 case, 27.6% lower, RR 0.72, p = 0.003, high zinc levels 110 of 188 (58.5%), low zinc levels 42 of 52 (80.8%).
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.
