Tldr; it might help to take zinc.
Out of 249 studied patients, there was 8% (21 patients) mortality. The investigators found a significantly lower plasma level of zinc in COVID-19 patients who died (43 μg/dl) than the patients who survived (63.1 μg/dl). After adjusting different variables, the investigators showed each unit increase of plasma zinc at the time of hospital admission resulted in a 7% reduced risk of in-hospital mortality.
It might aswell indicate that severe COVID causes reduced levels of zinc. Correlations need to be tested experimentally (e.g., like the vaccines).
Exactly. This is a preliminary study, and I’m worried that like with so many preliminary studies the anti-vaxxers will run with it as a substitute for vaccination.
