Data collected as part of a multi-country, population-based study to compare neonatal mortality risks by birthweight categories, gestational age, and newborn types.
We analysed routinely collected data on 125.5 million live births from 1 January 2000 to 31 December 2020 from 15 participating countries. Each country analysed their data and aggregated tables were shared online.
The Excel spreadsheet contains three worksheets / tables, each of which are described below. Each table has been exported to tab-delimited text format.
