Twiz, I thought the same thing about "may help improve", but on the other hand, in this situation he can't say anything that sounds definitive for obvious reason. I just like the fact that he even mentioned non-responders to responders, which is what this is all about.
He has to say "may." He would be opening himself up to lawsuits if he stated otherwise. Here's hoping the news is positive enough to move the needle upward. Ive owned this stock for 4 years and am underwater.
