What it does not show
The study is ecological and uses aggregate records, so it cannot evaluate individual-level maternal health factors. Possible inconsistencies in Live Birth Information System reporting could affect the rates. Missing or incomplete records were excluded, and lower totals in Table 1 indicate missing data. The analysis uses aggregate records rather than individual patient follow-up. The findings describe live birth records in Sergipe from 2013 to 2023.

The easy way to misread this
Do not read the decreasing trends as evidence that a specific maternity or neonatal intervention caused the improvement. This study describes aggregate birth records and cannot test causes.
