That claim is based on many studies, in fact it's the result of a meta-study.
Just so everyone knows, several meta-studies have been done by independent reviewers - most recently captured in the Cass Report, in the UK - and the meta-study conclusions are that there is no good quality evidence for the safety or efficacy of WPATH's GAC medical protocols, which are the de facto protocols used in the US.
The conclusions of these meta-studies - having reviewed hundreds of studies such as the few you just posted - is that, for a variety of reasons, none of them offer high quality data.
So I'll stick with the meta-studies
And if your next move is to try to discredit the Cass Report, it was commissioned by the UK's NHS, it was four years in the making, anyone can read it, and it was conducted using the highest research standards.
