To the Editor As authors of articles cited by Louis and Lampiris,1 we have a different view of the evidence that should inform recommendations about treating influenza with neuraminidase inhibitors.
Louis and Lampiris1 champion conclusions from observational studies.

However, we analyzed 13 such placebo-controlled randomized clinical trials in our Cochrane review.2
