The National Perinatal Epidemiology Unit (NPEU) is a multi-disciplinary research unit within the Nuffield Department of Population Health at Oxford University. It is located in the Richard Doll Building on the Old Road Campus, in Headington, east Oxford, England.
The unit's work involves randomized controlled trials, national surveillance programs and surveys and other research on maternal and infant health and care in the perinatal period (before, during and after birth).[1] The early work of the NPEU in developing a register of perinatal trials and methods for synthesizing their results lay the foundations for the Cochrane Collaboration.[2][3]
