Neural tube defect among newborns in public hospitals of Tigray region, northern Ethiopia: A cross-sectional study.
Article in PloS one, 2025. 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
backgroundNeural tube defects are serious congenital abnormalities caused by abnormal neural tube closure that occur between third and fourth weeks of pregnancy. Globally, neural tube defect is one of the top causes of morbidity and mortality among children under the age of five years. Ethiopia bears the highest adjusted mortality rate attributable to neural tube defects among sub-Saharan African countries. Despite this burden, neural tube defects remain understudied in Tigray, a region recently devastated by conflict.
objectiveTo assess the prevalence and factors associated with neural tube defect among newborns in public hospitals of Tigray, northern Ethiopia, 2024.
methodsA facility based cross sectional study design was conducted among 1155 newborns in randomly selected public hospitals in the Tigray region from April 1 to May 30, 2024. Study participants were selected using a systematic random sampling technique. Data were collected through interviewer-administered, pretested, and structured questionnaires. Variables with a p-value of less than 0.25 in the bivariate logistic regression were included in the multivariable analysis to assess their independent effects. Associations between dependent and independent variables were considered statistically significant at a p-value < 0.05.
resultsThe overall prevalence of neural tube defects in this study was 3%. Residence (AOR=3.37, 95% CI: 1.46-7.77), folic acid supplementation before and during pregnancy (AOR=0.14, 95% CI: 0.06-0.33), having no medical illness during pregnancy (AOR=0.10, 95% CI: 0.04-0.21), food consumption score (AOR=2.90, 95% CI: 1.10-7.82), and alcohol consumption during pregnancy (AOR=2.90, 95% CI: 1.30-6.45) were the determinants for neural tube defects.
conclusionsThe prevalence of neural tube defects is comparatively high among newborns born in Tigray's public hospitals as compared to previous studies. Residing in rural areas, folic acid supplementation before and during pregnancy, having no medical illnesses during pregnancy, poor food consumption scores, and alcohol consumption during pregnancy were the determinants for neural tube defects. Preventive strategies, such as periconceptional folic acid supplementation, folate fortification, promoting healthy dietary practices, avoiding alcohol consumption, early maternal screening, and treatment of medical illnesses, are essential at both regional and national levels.
