(If you haven't read and downloaded or archived this, consider doing so. I'm stunned that it exists on a government NIH website and don't expect it to be there for long). -- A short excerpt (bold added):

When this pandemic started, hospitals were ordered by the CDC to follow a treatment protocol that resulted in the deaths of hundreds of thousands of patients, most of whom would have recovered had proper treatments been allowed.[43,44] The majority of these deaths could have been prevented had doctors been allowed to use early treatment with such products as Ivermectin, hydroxy-chloroquine and a number of other safe drugs and natural compounds. It has been estimated, based on results by physicians treating the most covid patients successfully, that of the 800,000 people that we are told died from Covid, 640,000 could have not only been saved, but could have, in many cases, returned to their pre-infection health status had mandated early treatment with these proven methods been used. This neglect of early treatment constitutes mass murder. That means 160,000 would have actually died, far less than the number dying at the hands of bureaucracies, medical associations and medical boards that refused to stand up for their patients. According to studies of early treatment of thousands of patients by brave, caring doctors, seventy-five to eighty percent of the deaths could have been prevented.[43,44]
