I'd argue that the results might not be from the drugs but from the fact that they were heavily monitored by other humans.
It's not the drugs that people with high anxiety need, it's people giving them attention and caring for them.
These experiments need a control where they just take the drug and they don't have medical staff around.
"In this phase 2b, multicenter, randomized, double-blind, placebo-controlled study of 4 dose levels of MM120 that included 198 adults with generalized anxiety disorder, the primary outcome of a dose-response relationship for change in Hamilton Anxiety Rating Scale score at week 4 was statistically significant."
The control is where you have the medical staff around but not the drug. I believe placebo control groups are pretty common.
You are fabricating a lot of details about the study to come to that conclusion.
If only there were experts on the ground, designing the experiment, who could plan to avoid such interfering variables.
Isn't that basically the same as them using a placebo? If just care has the same effect, then surely heavily monitoring them while providing a placebo drug should work.
