You dont need a placebo group, when you have alot of samples with varying exposures. Focusing on the unvaccinated is a strawman.

Cleaning of data is really common practice in statistical analysis, you should declare it though. If you where tasked to summarize performance metrics in a company to find a base line, would you include days where eg. earth quakes hit?
- tialaramex 1y agoYou don't ever have placebo groups where we are confident that not intervening is unethical. Because he had the same cancer I think Hank Green might have a video about this, but years ago when I got diagnosed with Hodgkins I read the data and there's no placebo trials because scientific medicine (and thus placebo trials) was invented after they had some initial working cures for Hodgkins. So any fool can see a "placebo" trial is just arbitrarily killing a bunch of people to check a box which is awful and they never performed one. We still have excellent reason to believe Hodgkins would kill you because some people, despite being told what's wrong and that we can cure it, will say "No". Crazy, religious, I guess maybe in the US too poor (?) doesn't matter, they decline the cure and those people die, because cancer is bad for you. But they're self-selecting and so do not constitute a placebo trial. It seems ludicrous, but in theory maybe they only die because they're crazy or poor or they believe God will cure them or something. We can't prove it ain't so. We do still run trials, but they're not A vs Placebo, they take the existing "gold standard" treatment you would get if there wasn't a trial and they compare something they think could be better against that.
