The Cass Review is an independent report on the state of gender identity services for under-18s in England’s NHS. It found children had been let down by a lack of research and "remarkably weak" evidence on medical interventions in gender care. But before it was even released, claims were circulating online that it ignored 98% of the evidence in reaching its conclusion. Is that claim true? We speak to Dr Hilary Cass, the author of the review, Professor Catherine Hewitt of York University, who analysed the scientific research, and Kamran Abbasi, editor in chief of the British Medical Journal.
