Evidence and findings
One hundred fifty women with cyclic mastalgia were randomized to vitamin E or placebo for four months. Pain severity and duration were assessed with breast-pain charts and visual scales. [1]
The report described an advantage over placebo at two and four months, without a significant additional difference between those treatment durations. The measured question concerned cyclical pain. [1]
Interpretation and limits
Cyst disappearance, diagnosis of a new breast lump and long-term breast outcomes were not established by the reported endpoints. Funding and conflicts were not established from the abstract. Symptom improvement in a trial should not substitute for assessment of a new or changing breast finding. [1]
A hypothetical distinction
Imagine discomfort decreases while no imaging outcome was collected. The symptom result cannot show that an underlying structural finding disappeared.
| Detail | Interpretation |
|---|---|
| Pain score | Measured symptom |
| Cyst resolution | Different endpoint |
| New breast finding | Requires assessment |
