Hyperbole in the battle of Zevalin vs Rituxan in Follicular Lymphoma?

OK all you Follicular lymphoma types, how's this for hyperbole?

"A single infusion of Zevalin matched roughly 16 infusions of rituximab in terms of achieving the same increase in [progression-free survival] … [Zevalin] represents the most effective single 'drug' in the treatment of follicular NHL. No doubt about it." [my emphasis].

This is from an oral discussion "006: Zevalin Consolidation vs. Rituximab-Maintenance in First Remission Follicular Non-Hodgkin’s Lymphoma – The Case for RIT" that took place in June during the 11th International Conference on Malignant Lymphoma. Read the full summary HERE (#006).

Sound like hyperbole? As enamored as I am of Zevalin, this to me seems a bit over the top.

Thank you for the insight and information Ross! As always, you are such a wealth of information.
