Water, sanitation, and hygiene and nutritional status of children under-5 years born to young mothers in Ghana: a spatial inequality analysis.

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: Malnutrition among children under five remains a major public health challenge in sub-Saharan Africa, with those born to young mothers being particularly vulnerable. Evidence on the role of water, sanitation, and hygiene (WASH) in this subgroup is limited in Ghana. We estimated the association between WASH and childhood malnutrition, and characterized its spatial and socioeconomic distribution, in young mother-child pairs in Ghana. Methods: We analyzed 620 child-mother pairs (mothers aged 15-24 years) from the 2022 Ghana Demographic and Health Survey. Outcomes were stunting, wasting, and underweight, defined using WHO growth standards (< -2 SD). Survey-weighted multilevel logistic regression examined WASH-nutrition associations. Spatial patterns were assessed using Global Moran's I, and LISA and Getis-Ord G*. Socioeconomic inequality was measured via concentration indices, the Theil T index, Lorenz curves, and difference/relative indices. Population attributable fractions (PAF) and risks (PAR) were estimated for binary WASH exposures. Results: Stunting prevalence was 18.8% (95% CI 15.5-22.6), wasting 8.7% (6.2-11.9), and underweight 15.6% (12.4-19.4). Volta Region recorded the highest observed weighted prevalence for all three outcomes (stunting 32.0%, wasting 16.8%, underweight 39.4%), but these estimates were based on a small subsample (unweighted Conclusion: Malnutrition among children of young mothers in Ghana is unevenly distributed and concentrated among socioeconomically disadvantaged populations. Equitable WASH services, alongside targeted nutrition programming, may help reduce nutritional inequalities in support of SDG 2 and SDG 6.
