Selenium, zinc, and vitamin D supplementation affect the clinical course of COVID-19 infection in Hashimoto’s thyroiditis
Retrospective 356 Hashimoto's thyroiditis outpatients, 270 taking vitamin D, zinc, and selenium, showing significantly lower hospitalization with treatment. Authors adjust for age, gender, BMI, and smoking status, reporting statistically significant associations with
p<0.001 for hospitalization and mechanical ventilation, however they do not report the adjusted risks.
Asimi et al., 5/22/2021, retrospective, Bosnia and Herzegovina, Europe, preprint, 3 authors, this trial uses multiple treatments in the treatment arm (combined with vitamin D and selenium) - results of individual treatments may vary.
risk of mechanical ventilation, 97.4% lower, RR 0.03, p < 0.001, treatment 0 of 270 (0.0%), control 9 of 86 (10.5%), continuity correction due to zero event (with reciprocal of the contrasting arm), unadjusted.
risk of hospitalization, 99.0% lower, RR 0.010, p < 0.001, treatment 0 of 270 (0.0%), control 24 of 86 (27.9%), continuity correction due to zero event (with reciprocal of the contrasting arm), unadjusted.
risk of COVID-19 severe case, 99.5% lower, RR 0.005, p < 0.001, treatment 0 of 270 (0.0%), control 51 of 86 (59.3%), continuity correction due to zero event (with reciprocal of the contrasting arm), unadjusted.
This study is excluded in meta analysis: excessive unadjusted differences between groups.
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.
