Yes. Exactly exactly. The whole point of having a placebo or SOC arm is to compare to a STANDARD, so anyone can see what benefit the drug has. But when one drug is compared to a mortality rate of, say 32%, and another drug is compared to a mortality rate of 21%, how can the result help us compare the two drugs?
It's no longer an accurate measure of how well the drug works.
We've had enough Covid cases and deaths now so we should be able to KNOW how many people die under various circumstances. Compare the drugs to what we know; we don't need a measurement against a skewed "standard" of care.
