Studies can be designed to fail.
HCQ and Ivermectin work in combination with zinc and other drugs when given early on in the course of the disease.
Studies of just the HCQ and Ivermectin without the zinc included prove nothing.
Studies done on the meds given to critically ill patients prove nothing. Neither drug is reputed to reverse organ damage done by not treating the disease to prevent it from getting to that point.
The dosage of the meds needs to be correct.
There are plenty of ways to fix studies to get the results you want.
And big pharma and the left did not want anything to interfere with their ability to get the EUA for their alleged vaccine, thus the studies done would be designed to fail.
Another way I have found that they mislead with data is through “metanalysis” that include flawed studies. They know that most people will not look at the studies one by one.
There was a metanalysis like that posted here with 10 studies, one study never even finished, one was fatally flawed because they changed the parameters halfway through, and another had incorrect calculations. All 3 had letters to the journals calling for retraction. Anyway, they get buried in these metanalyses which is being used to push the narrative.
Ivmmeta.com is the one source I have seen that lists most studies that exist and discusses them one by one. They chose only the ones that are not flawed to do their analysis and the results are consistent nearly across the board. It is a tremendous resource.
