Changed? I was always under impression from company that results would be presented later in April. People are hanging too much on the Q1 thing. Just says testing completed 'around' end of Q1. Company stated April for communication a while back I read somewhere. Possible there is an issue, but I don't believe so.

That said, the clinical testing results coming in Q2 don't concern me that much. If "trial" finishes at the end of the Quarter, results in Q2 seem natural.
