The study and its comparison
Sixteen participants were randomized to supervised repeated psilocybin or placebo sessions; fourteen entered the final analysis. Headache diaries continued for eight weeks after the first session. [1]
The early attack-frequency comparison was not significant, with p=0.251 and wide confidence intervals. Larger effect sizes in a chronic-headache subgroup were exploratory. [1]
What the finding establishes
A small study may miss an effect, but lack of power does not turn a negative result into proof of benefit. Cluster headache is also not every chronic-pain condition. Funding and conflicts were not established from the abstract. The study does not support unsupervised treatment or delaying established headache care. [1]
A hypothetical distinction
Imagine a subgroup estimate looks large but uncertain. Its size alone does not settle whether treatment works.
| Detail | Interpretation |
|---|---|
| Measured outcome | Keep the endpoint specific |
| Study preparation | Not every retail product |
| Remaining uncertainty | Not resolved by a mechanism |
