Maternal anaemia and risk of neonatal and infant mortality in low- and middle-income countries: a secondary analysis of 45 national datasets.
Article in BMJ global health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundAnaemia in pregnancy has been recognised worldwide as a growing public health concern and an important cause of adverse neonatal outcomes. However, only a limited number of studies have been done in low-income settings, which have the highest prevalence of anaemia. We aimed to investigate the association between maternal anaemia and neonatal and infant mortality in low- and middle-income countries.
methodsSecondary analysis of pooled data from 45 national demographic and health surveys (2010-2020). We included all women between 15 and 49 years old, who had singleton live birth within 1 year preceding the survey, with a valid maternal measurement of haemoglobin. We used logistic regression models to estimate the crude and adjusted OR (aOR) with 95% CIs of the association between maternal anaemia (measured at the time of the survey) and the risk of neonatal and infant mortality.
resultsAmong 106 143 women included in our analysis, there were 53 348 (50.5%) women with no anaemia, 24 670 (23.2%) with mild anaemia, 25 937 (24.3%) with moderate anaemia and 2188 (2.0%) with severe anaemia. Overall, there were 2668 (2.5%) neonatal and 3756 (3.5%) infant deaths. Moderate (aOR 1.20; 95% CI 1.06 to 1.35) and severe (aOR 1.89; 95% CI 1.46 to 2.44) maternal anaemia were associated with increased odds of neonatal mortality, respectively. Similar estimates were observed for moderate and severe anaemia and infant mortality. No increased risk was noted for mild anaemia.
interpretationModerate and severe maternal anaemia in low- and middle-income settings are associated with increased risks of neonatal and infant mortality. Future research should examine how targeted interventions for prepregnancy and antenatal treatment of anaemia in reproductive-age women can enhance maternal and child health in low- and middle-income settings.
