So, it's true to say that out of the follow up group of 930 patients, 59 were deceased and 19% of those (i.e. 11 patients) had killed themselves.
@CBS We cannot know what the lifetime mortality from suicide is going to be from the group because 871 of them are still alive. It isn't legitimate to assume the rate is going to remain the same at all stages of life. Therefore it cannot be claimed that one in five patients kill themselves.
We have two small studies with reasonably close percentages of suicide amongst those who could be confirmed as dead. You are right to say that we that we don't know what the rates may be for the remaining patients (actually 960 completed follow-up surveys, a small percentage refused to participate, I think it was under 30 or so, and the remaining 300+ were lost to follow-up after extensive efforts including searches of the Federal Death Registries - based upon state medical examiner reports - and no other disposition could be achieved) who are alive.
There may be patients who have hung on waiting for something to happen and then lose hope when project X or Y fails to come through. Someday soon there may be a biomarker that points to a cure for some or all patients. At present, all we have to go on are past events and of the deaths that were confirmed, roughly 1in 5 patients from those co-horts had committed suicide. The title was deliberately worded "As many as..."
