Was this Ivermectin Study Flawed From the Start? The Principle Study

The Principle Study was a large UK study conducted by prestigious researchers and peer-reviewed in the Journal of Infection. Researchers claimed the result of the study was that Ivermectin did not help treat Covid-19. The study has been lauded, but is it Verified? (EDIT: I should have added that Ivermectin is said to work by super-charging zinc in its action against pathogens and should be taken WITH zinc and vitamin D. This was not done in the study. The study could have given both groups zinc and vitamin D for a more applicable test.
