I’ve seen these corrupt big pharma trials many times over the decades. If a drug MUST NOT be mixed with grape jelly for it to be effective, by golly, every trial participant will be given a peanut butter and jelly sandwich for lunch. Or if zinc nullifies the positive effect, by golly, all trial participants are fed foods high in zinc. Corrupt as hell.
The study in this thread is what you are talking about: Malaysian Study Finds Ivermectin ‘Did Not Prevent’ Severe COVID-19, but Doctors Alliance Calls It ‘Misleading’. This study used a dose of Ivermectin no one is advocating on patients with mild to severe cases and found that major side effects were the same. The 70% reduction in death was not important.
The study in the WSJ article about people who were at risk of a severe case of Covid. So this looks like it was set up to ensure failure of what no one is calling for.
