Adherence to solar disinfection water treatment reduces diarrheal incidence among children in Malawi: a secondary analysis of a cluster quasi-experimental study.
Article in Journal of water and health, 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
backgroundDiarrhoea is a leading cause of morbidity and mortality among children under five in low-income regions. This study assessed the effectiveness of household solar disinfection (SODIS) in reducing diarrhoeal incidence among children in Chikwawa District, Malawi.
methodsWe conducted a secondary analysis of a cluster quasi-experimental trial (March 2019-March 2020) involving 985 children from 793 households: control (369 children, 271 households), 20 L transparent polypropylene SODIS bucket (336 children, 258 households), and SODIS bucket with cloth filter (380 children, 264 households). Variables included water source, child age, sex, rotavirus vaccination, SODIS adherence. Analyses employed descriptive statistics, Chi-square, Kruskal-Wallis tests, and Poisson regression with robust standard errors in Stata 17.
resultsOverall, diarrhoeal incidence was two cases per child-year. Households using SODIS buckets had an 88% reduction in incidence (adjusted incidence rate ratio (IRR): 0.12; 95% CI: 0.04-0.23), while those using SODIS with a cloth filter saw a 70% reduction (adjusted IRR: 0.30; 95% CI: 0.18-0.50). High SODIS adherence was linked to 90% reduction (adjusted IRR: 0.13; 95% CI: 0.02-0.81); medium adherence showed no significant effect.
conclusionThese findings support SODIS as an effective point-of-use water treatment, with adherence critical to health impact.
