Statistical analysis plan for a cluster randomised trial in Madhya Pradesh, India: community health promotion and medical provision and impact on neonates (CHAMPION2)

Abstract Background Neonatal mortality in India has fallen steadily and was estimated to be 24 per 1000 live births in the year 2017. However, neonatal mortality remains high in rural parts of the country. The Community Health Promotion and Medical Provision and Impact On Neonates (CHAMPION2) trial investigates the effect of a complex health intervention on neonatal mortality in the Satna District of Madhya Pradesh. Methods/design The CHAMPION2 trial forms one part of a cluster-randomised controlled trial with villages (clusters) randomised to receive either a health (CHAMPION2) or education (STRIPES2) intervention. Villages receiving the health intervention are controls for the education intervention and vice versa. The primary outcome is neonatal mortality. Secondary outcomes include maternal mortality; stillbirths; perinatal deaths; causes of death; health care and knowledge; hospital admissions of enrolled women during pregnancy or in the immediate post-natal care period, or of their babies (during the neonatal period); maternal blood transfusions; and the cost effectiveness of the intervention. A total of 196 villages have been randomised and over 34,000 women have been recruited in CHAMPION2. Discussion This update to the published trial protocol gives a detailed plan for the statistical analysis of the CHAMPION2 trial. Trial registration Registry of India: CTRI/2019/05/019296.
