Targeting undernutrition in Haiti: a spatial analysis for improving food security and reducing stunting in children under five.
Article in Public health nutrition, 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
objectiveThis study aims to contribute to enhanced food security in Haiti through proposing targeted local interventions. Employing a spatially explicit tool, the research supports decision-making by relating undernutrition to socio-economic conditions and biophysical factors.
designGeoreferenced Demographic and Health Survey (DHS) conducted in 2016–2017 combined with spatial environmental information was used for a multivariate linear regression model to identify factors associated with stunting prevalence. Missing data were imputed through kernel density regression. We converted the structural relationship estimated for the territory of Haiti into a decision support tool by adding fixed effects at communal level. Various policy scenarios were analysed.
settingHaiti, with spatial data across the 134 communes.
participantsThe analysis included 5623 children under five and their mothers, sourced from DHS data.
resultsApproximately 22 % of all children were stunted. Implementation of the LimitedIntervention development scenario led to a 2·5 % reduction in stunting, while the ModerateIntervention and FullIntervention scenarios achieved more significant reductions of 6 % and 10 %, respectively. Areas with highest stunting incidence benefit most from interventions.
conclusionsThis tool supports decisionmakers by assessing the impact of interventions at commune level and selecting areas where interventions exert the most significant effects. The study suggests to apply a strategy that starts in relatively safe communes and then scales to other areas. The flexible approach adopted in this study allows applications in other countries or regions to assess the prevalence of undernutrition among children under five.
