We have a small community that collects data together about treatments and symptoms. One of those is Cluster headache. In 2 plots of attacks and treatments we see on n=1 level an influence of one of the treatments taken.
In the first one its a very serious patient that takes a Prednisone presciption 2 time over 2 years. You see a clear gat that other treatments don’t seem to have.
In the other one it someone with less attacks taking Magic Mushrooms. During the use you see less attacks and after it its gone. Could be a coincidence
