The study actually looked at the outcome in a large sample of patients with laryngeal cancer over a long follow-up period. However, we have 2 reservations regardng the way the analysis was performed and the conclusions that were drawn from the analysis.

A significantly low survival rate was shown for . . . [Full Text of this Article]
