No, I understand.
General, again, I seem to be in the habit of asking very difficult questions, and I don't know if there's data about this. We do know that PTSD itself is an unfortunate and tragic occurrence in personnel who deploy in any combat situation. We have personnel who deployed in different theatres in different parts of the world, in some of which malaria is not an issue, so you wouldn't be prescribing antimalarial prophylaxis because they wouldn't need it.
Do we have any data on rates of PTSD diagnosis in soldiers in theatres where they've served and this was not an issue, and we know we would not have had any antimalarial prophylaxis because it wasn't an issue, versus in theatres where you had to have such prophylaxis?
