A politically motivated "review" masquerading as meta-analysis in which Dr. Hillary Cass purposefully tuned their demands for good-enough evidence as so
far to exclude every
single study that don't fit their beliefs. In order to do that, she excluded 98% of studies that aren't
high-quality (ie. those that aren't double-blinded or didn't had a control group, despite their obvious impossibility). This allowed her to pull out the conclusion that she wanted.
What's the point of low-quality studies if they are useless? If they were, they wouldn't be done anymore.
Not only that, the voice of trans
people were dismissed as "biased" so that she doesn't have to comfort with uncomfortable truth.
