Thanks. Although the language is for a control group with placebo only, the language, “invasive procedure,” is enough for me (also because of things the message board covered in the past) That explains the halt, IMO.
A (possible) additional (internal to this trial) bridge study of sorts, might explain why we went out this far. Dr. Boynton, many years ago foresaw a much longer trial if optimization occurred, so at the time he leaned against it, but, optimization might have occurred to one degree or another, as exhaustively debated here long ago — this possibly extending this trial.
