Sufficient for what? It isn’t sufficient to have a 75% confidence in your conclusion. Three anecdotes isn’t even high enough to have 50% confidence. It’s laughably low.
But what conclusions do you think you can draw from those three anecdotes? I’m really curious.
Not for this experiment. If the probabilities were different, a sample size of three might be meaningful, but not for Ivermectin and Covid. It’s hard to demonstrate effectiveness of “something” if it is hardly different in outcomes than the “no something” case.
So we are still where it may or may not work. As opposed to an anti viral that has strong evidence of working. I know which I would choose assuming doctor’s recommendation.
Even the COVID Hunter doctor in Houston admits that although it is part of the early therapy cocktail he gives his patients with COVID, it’s so early in the game…and the cocktail contains so many other things…that it’s hard to say definitively which part of the cocktail is providing the beneficial effect.
