Please show us a serious correct study that gave this result with HCQ,Zinc plus Doxycycline??
That exact combination I don't have RCT evidence for. But if you require that - you also lose all the anecdotal positive evidence!
For example this one does not include Zinc.
A total of 11% (n=6) patients were transferred to acute care hospitals due to clinical deterioration and 6% (n=3) patients died in the facilities. Naive Indirect Comparison suggests these data were significantly better outcomes than the data reported in MMWR (reported on March 26, 2020) from a long-term care facility in King County, Washington where 57% patients were hospitalized, and 22% patients died. Conclusion: The clinical experience of this case series indicates DOXY-HCQ treatment in high-risk COVID-19 patients is associated with a reduction in clinical recovery, decreased transfer to hospital and decreased mortality were observed after treatment with DOXY-HCQ.
And my point, well justified by factual evidence and theory - is that Naive Indirect Comparison is a very poor way - effectively useless - to judge a treatment.
