Let me know if there's already a thread on this, I can't see one. Jesse Singal has a very good two part Substack on the fiasco at McMaster.
SEGM funded five systematic reviews of different aspects of gender affirmative treatments. The research team included Gordon Guyatt, the man who in 1991 coined the term "evidence based medicine". The SRs found (unsurprisingly) that the evidence was very poor.
The research team and the university were both targeted by trans activists. SEGM have been branded a hate group, and Guyatt and colleagues have been denounced for working with "a hate group".
The researchers (not all, but this includes Guyatt) have variously scuppered the publication of some of the reviews; added notices on how the SRs should affect policy (eg that they should not be used to support bans on puberty blockers) and have given apology money to a trans charity that disseminates false information on these treatments.
