Prof. Carl Heneghan and Prof. Ben Goldacre begin EBM critique of Letby evidence

Prof. Carl Heneghan (Oxford Centre for Evidence-Based Medicine) and Prof. Ben Goldacre (Bennett Institute; Bad Science framework) begin sustained public commentary applying the EBM framework to the Crown's Letby trial evidence. Both identify four specific EBM failures: retrospective pattern-matching without pre-registration, absence of control, hypothesis-first reasoning, non-peer-reviewed methodology. The institutional UK EBM community's judgment is that the Crown's methodology does not meet EBM standards.
