Environmental enteric dysfunction in well-nourished and undernourished women in Bangladesh.
Article in BMC gastroenterology, 2026. 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
introductionEnvironmental Enteric Dysfunction (EED) is a subacute inflammation of the small intestinal (SI) mucosa associated with undernutrition and perturbation of the SI microbiota. Its diagnosis relies on histopathological assessment of small intestinal biopsies, with a lack of validated biomarkers contributing to underdiagnosis. This study assessed the prevalence and histological features of EED in undernourished Bangladeshi women living in an urban slum in Dhaka, compared to well-nourished women from slum and non-slum areas, and examined the factors associated with histologically confirmed EED.
methodsThis analysis included non-pregnant, non-lactating Bangladeshi women aged 18-45 years classified by location of residence and nutritional status: well-nourished non-slum residents (WNNS), well-nourished slum residents (WNS), and undernourished slum residents (UNS). Data were obtained from two ongoing studies and one completed study. Well-nourished women (BMI 20-24.9 kg/m
resultsBetween October 2, 2022, and June 30, 2024, 1059 WNNS and 445 WNS women were screened for eligibility. Of these, 33 WNNS and 55 WNS women underwent endoscopic evaluation. Histological data were available from a prior study of 38 UNS women. Histological examination showed EED in 21% of WNNS, 18% of WNS, and 100% of UNS women. Multiple logistic regression analysis indicated that BMI (aOR: 0.70, 95% CI: 0.58-0.85; p < 0.001) was significantly associated with the presence of EED in women in this study.
conclusionAlthough EED was expectedly common in undernourished women, its detection in well-nourished women indicates that environmental conditions may influence intestinal health beyond nutritional status alone. These findings indicate that attention to environmental risks is important for wider groups of women and support further work to understand the pathways that lead to EED in different community settings.
