This alone should shut you up. Any scientific dispute will identify the trials they assess. What you have posted is miss information and propaganda. Unless and until the data is shown publicly, whereby other scientist can verify it, it’s bullshit. Stop repeating the same line that no trials were found to show ivermectin was efficacious as a treatment for Covid. The article you posted have not reviewed the trials conducted that shows that ivermectin was efficacious,.
A blanket statement simply saying no trials have shown efficacy is pure nonsense based on propaganda rather than on real science.
it’s a statement to make lazy people believe that it’s true without any evidence to show its fact.
