Do you (or anyone else) have a good link or data on the various efficacy rate of the Interferon's in MS (and Tysabri). Or is it better to not be lazy and just read the labels? :-)
As I have posted (on the PLX board), having 21 extra patients seemed too little to me. Adding 100 more, so the majority (~150) of patients will have access to the 0.25mg pill, makes a p-value of 0.01 in this trial achievable, imo.
