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
Background Maternal and neonatal mortality remains a critical public health challenge in low- and middle-income countries, particularly in South Asia and Southeast Asia. Despite progress, regional disparities persist, and the influence of socioeconomic and health system factors varies across contexts. This study aimed to comparatively assess determinants of maternal mortality ratio (MMR) and neonatal mortality rate (NMR) across these regions. Methods An ecological longitudinal panel study was conducted using data from the World Bank for 19 countries (2010-2023). Outcomes included MMR and NMR, while explanatory variables were health expenditure, gross domestic product (GDP) per capita, adolescent fertility rate (AFR), anaemia prevalence among pregnant women, and a COVID-19 indicator. Log-transformed variables were analysed using fixed and random effects regression models, with Hausman tests guiding model selection. Stratified and interaction analyses assessed regional differences. Results Both regions showed declining mortality trends, though South Asia consistently exhibited higher MMR and NMR. GDP per capita was inversely associated with both outcomes across regions. In South Asia, health expenditure and GDP were protective, while AFR significantly increased both MMR and NMR. In Southeast Asia, anaemia prevalence emerged as the strongest predictor of increased mortality. The COVID-19 period was associated with a significant rise in maternal mortality but not neonatal mortality. Interaction models revealed stronger effects of health expenditure in South Asia. In addition, the association between adolescent fertility and mortality differed by region, being negative in Southeast Asia but positive in South Asia, indicating a reversal in the direction of association across regions. Conclusion Maternal and neonatal mortality outcomes in South Asia and Southeast Asia are associated with region-specific socioeconomic, demographic, and health-system factors. Economic development is protective, whereas adolescent fertility and maternal anaemia are key risk factors. Targeted, context-specific interventions focusing on strengthening health systems, reducing adolescent pregnancies, and addressing maternal anaemia are essential for further mortality reduction.
