Experts call for Lucy Letby inquiry to cover statistical evidence used in trial

Royal Statistical Society suggests a better understanding of statistics could help NHS trusts act more quickly in similar cases

The Royal Statistical Society (RSS) is calling for the Lucy Letby inquiry to cover statistical evidence used in the trial of the serial baby killer, saying it can be difficult to draw conclusions from suspicious clusters of deaths" in hospitals.

In August, Letby was found guilty of murdering seven babies and attempting to kill six more at the Countess of Chester hospital, making her the worst child serial killer in modern British history.
