Flow diagram

Flow of participants from ascertainment of stillbirth and deaths in children younger than 5 years to CHAMPS enrolment, MITS consent, cause of death determination, and neural tube defect anywhere in the causal chain, by site. Where 2021 HDSS data were not available, 2020 HDSS data were substituted. CHAMPS=Child Health and Mortality Prevention Surveillance Network. DeCoDe=determination of cause of death. MITS=minimally invasive tissue sampling. HDSS=health and demographic surveillance systems. *Eligible stillbirths and deaths in children younger than 5 years never enrolled in CHAMPS. †Deaths enrolled in CHAMPS not eligible for or refused MITS.
