Seen the “98% of studies were ignored!” one doing the rounds on social media. The editorial in the BMJ put it in much better terms:
“One emerging criticism of the Cass review is that it set the methodological bar too high for research to be included in its analysis and discarded too many studies on the basis of quality. In fact, the reality is different: studies in gender medicine fall woefully short in terms of methodological rigour; the methodological bar for gender medicine studies was set too low, generating research findings that are therefore hard to interpret.”
And of the 103 reviewed they included data from 60. It is a lie to say they “dismissed all but two.”
So you don’t know what you are talking about. Gotcha.
You can read the reviews for yourself

Let me know where you find the bit where they dismiss 101 out of 103 papers.
Read it. Their only inclusion in the report is to half explain why the were discluded, exactly what I said. Most of the dismissals are unscientific. Data doesn’t become unreliable just because it is incomplete.
That report is absolutely rife with white washing and selection bias, I’d expect a scientific review of trans literature and studies to be a book at this point not 32 pages dismissing 98% of the data. It’s frankly insulting to anyone that’s read or written any number of scientific studies.
They did not dismiss 98% of the data.
Putting 98% of the relevant available data in supplementary table 4 is not including the data.
Supplementary Table 4 (from the first review) is a list of each of the 53 studies included in the review and how they were scored based on the Newcastle-Ottawa scale.
The “data” is in supplementary tables 3, 5, 6 and 7. Only studies that were scored as low quality were excluded from the synthesis.
“They dismissed 98% of data” is a lie.
No it’s not. None of the dismissals are statistically/ scientifically supported, and the data they present is blurbed and incompletely presented in a way that isn’t inclusive of what those studies actually say.
Nothing was dismissed at all (and “statistics” has nothing to do with it so curious to mention it).
Studies were scored for quality on the well established Newcastle-Ottawa Score. High and Moderate quality studies were included in the synthesis. Low quality studies were not, but their outcomes are still reported.
Outcomes from each study were included in tables 3, 5, 6 and 7.
'They dismissed 98% of the data" remains a lie.
