¹Data collected, but neonatal mortality rate not disaggregated in the reports

²Stillbirth rates only available from surveys in countries with high contraceptive prevalence using model questionnaires 2A and 3A

³Proportion test comparing the mean stillbirth rate or mean neonatal mortality rate by survey module in each DHS phase: p = 0.016 in ^¹; p = 0.026 in ^³; p = 0.020 in ^³

⁴Trend test comparing SBR:NMR for each maternity history type found “no trend” across the ordered DHS phases (full birth history: p = 0.949 and full pregnancy history: p = 0.317)

⁵DHS refers to the Demographic and Health Surveys; SB refers to stillbirths; NND refers to neonatal deaths; NMR refers to neonatal mortality rate; SBR refers to stillbirth rate; and ENMR refers to early neonatal mortality rate
