Caraballo said: “I stand by my original statement, which described how the Cass review excluded 43 studies from the synthesis while several moderate quality studies showing positive outcomes were referenced in the results section but were ignored entirely in the conclusion.
“Ultimately, the Cass review disregarded a substantial portion of the available medical evidence based on subjective criteria.”
I particularly enjoyed the final sentence. The Cochrane Handbook is online and free to access for people who want to see the defined criteria for grading evidence, what is included in the systematic review and meta-analysis, what is included in a narrative review or discussion etc.
The criteria are set out in lucid and extensive detail. Harvard, Caraballo's employer, might wish Caraballo to read it before enmeshing them in further reputational harm about the quality of some of their staff appointments.
