Biogen & Serono continue marketing battle

The Boston Globe reports on the continuing battle between Biogen and Serono over which is more effective. Personally, I find these relative comparisons tiresome since the result is always that they are basically equally ineffective. If the differences were 30% compared to 80% - that would be worth knowing, but the money and effort and energy to show that both drugs don't help many people very much (but to slightly differing degrees) just all seems wasted to me.
