Editorial interpretation
Why it is interesting#
A clinical severity score and a patient's satisfaction capture different aspects of benefit.
Always state which outcome remains improved at the quoted timepoint.
What it cannot tell us#
- A single treatment and indication; the findings are not a brand-wide duration claim.
- These are different endpoints in the active group, not two competing products.
