First paragraph (this article has no abstract)

We read with great interest the article by Fourrier and colleagues [1], who investigated functional markers to predict the need for prolonged mechanical ventilation (MV) in patients with Guillain-Barré syndrome (GBS) and acute respiratory failure. The study was well conducted, but we are concerned about the study design and the confounding factors.
