Zinc Deficiency Associated With an Increase in Mortality in COVID-19 Patients: A Meta-Analysis.
Review in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The exact role of zinc in COVID-19-infected patients is not well understood. We examined the effects and outcomes of zinc deficiency on COVID-19-infected patients. We focused on patient outcomes: severity, symptomatology, and mortality. The meta-analysis was performed to examine whether COVID-19-infected individuals suffered greater symptomology and mortality. Secondary outcomes explored included severity and hospital length of stay. For mortality, we found that COVID-19-infected individuals with zinc deficiency had a greater risk of mortality than individuals without zinc deficiency (risk ratio (RR)=5.77; 95% confidence interval (CI): 3.48, 9.54; p=0.004). For symptomology, we found that COVID-19-infected individuals with zinc deficiency had a greater risk of symptomatology than individuals without a zinc deficiency (RR=1.39; 95% CI: 1.13, 1.70; p=0.020). Zinc-deficient individuals are at a greater risk for mortality and symptomatology. Our findings further reinforce the importance of supplementation as a prophylactic agent against viral infections such as COVID-19.
