Maternal mortality in Italy estimated by the Italian Obstetric Surveillance System.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This study aimed to calculate Italy's first national maternal mortality ratio (MMR) through an innovative record-linkage approach within the enhanced Italian Obstetric Surveillance System (ItOSS). A record-linkage retrospective cohort study was conducted nationwide, encompassing all women aged 11-59 years with one or more hospitalizations related to pregnancy or pregnancy outcomes from 2011 to 2019. Maternal deaths were identified by integrating data from the Death Registry and national and regional Hospital Discharge Databases supported by the integration of findings from confidential enquiries conducted through active surveillance. Maternal Mortality Ratio (MMR), direct MMR (DMMR), and causes of maternal death are the study main outcomes. The MMR was found to be 8.4 per 100,000 live births (95% CI 7.5-9.3), significantly higher than the 3.9 per 100,000 (95% CI 3.3-4.5) calculated solely from the Death Registry, with a notable declining trend over the study period. Causes of death have been classified according to the 10th International Classification of Diseases. Within 42 days from pregnancy outcome, leading causes were obstetric haemorrhage, sepsis, and cardiovascular diseases. Late maternal deaths were primarily attributed to suicide, malignancies, and cardiovascular diseases. This integrated methodology provides a comprehensive understanding of maternal mortality trends and causes in Italy, offering valuable insights for countries utilizing or planning enhanced surveillance systems.
