Prof. John O'Quigley publishes peer-reviewed analysis of the roster chart

Medicine, Science and the Law publishes 'Use of roster charts in the investigation and prosecution of nurses suspected of inflicting deliberate harm on patients' by Prof. John O'Quigley (UCL). The peer-reviewed paper analyses the statistical information in the roster chart — including the shifts of the 37 other nurses — and concludes that, from a forensic statistical point of view, the chart should not have been put before jurors.
