Scotty stated Les acknowledged event rate dropped to barely over 1 patient per month by summer 2018. Scotty was right about SNO 2018 revealing updated data, so benefit of doubt on event rate. Event rate now likely well below 1/month, imo. Age attrition likely becoming an important factor, with many patients in mid 70s and some entering 80s.
(Oldest person at baseline was 73.)
(Sadly, U.S. average life span for males has dropped back to 76.)
