I'm fairly certain it's attempts now that I've looked at it again. It's been a long time since I've read breakdowns of the studies and what the numbers all mean. It wasn't as simple as 41% of trans people attempt suicide. The numbers went down post transition and I don't think suicide attempts had to be serious attempts to be counted (I think it's worth nitpicking this).

Edit: Tried finding the survey the number comes from and got a bunch of different responses that are just confusing me more at this point. I'm probably done here, since researching suicide statistics isn't a ton of fun.
