Explained:

The doctors in many countries used HCQ+ Zinc+ etc. and this reduced the death-rate by a factor of 10, compared to those that did not get that treatment. This can even be seen in the stats per country.
As many different doctors with many patients (1,000 to 10,000+) in different countries get the same kind of results. This makes a very good case that this is a working medicine,

They needed to start the treatment early, when the viral load was rising. At later stage, the inflammation of the immune system becomes the problem and other medicine are needed. This was well known by the doctors.

But "scientists" connected to big medical companies, repeated this by using wrong methods (like using HCQ at late stage) and were able to have no reduction of deaths, and some even increase the number of deaths by poisoning the patients with overdoses. Also they were able to use fake data or inaccurate internet data or complete different control groups. And with the help of "friends" they got this fake science widely published in peer-reviewed journals.
This fake science has resulted in some important political decisions and has costed many lives.

This all clearly means that they were setting up the studies to fail, because they were working for a company that wanted to get a profit out of this crisis (unlike the doctors).

The fake scientists kept on publishing more bullshit science, but they were unable to repeat the reduction in deaths.
Because the doctors already have so much success with their methods, it clearly proves that the scientists have NO EXPLANATION for the reduction of deaths.
They could not proof that the 90% reduction in deaths could be attributed to anything else than the HCQ+ etc method. And they all failed to simply repeat the method as was well documented by the doctors.

These "scientists" only proved that they were completely corrupt!
