My guess would be within 3 months after top-line that they'd be presenting detailed data at a meeting. But it might depend on when the top-line comes out and when the next big meeting is. Here's a rough estimate of when the big diabetes/cardio meetings are between Q4 2018 and Q4 2019. There seems to be a "dead zone" between American Heart in November and American College of Cardiology in March. If I missed any big meetings on this list, I apologize and please add in.
