Here's what I posted, and yanked before I thought anyone had responded.  All y'all are too fast on the responses.....

    ....My previous (incorrect?) understanding was that when 250 unconfirmed 1st MACE events (I'll call them raw events) occurred, that this triggered the end of the dosing, the beginning of patient follow ups and the beginning of the adjudication process....

That still looks correct to me according to (FWIW) the presentation info, e.g., Jan page 19, the following point says: Adjudication of all MACE events ... post trial completion.

3. Adjudication of all SAE MACE events expected to take two to three months post trial completion.
