You missed the part where he had been on oral finasteride for a year already at that point (before switching to a very low dose topical dutasteride), so it's not that clear cut
I believe all of the participants died but they only recruited 20 patients so could've just been placebo/coincidence. They will run a trial with more patients to make sure
