Water and sanitation factors associated with schistosomiasis and soil transmitted helminthiasis persistence in Rwanda.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Schistosomiasis and soil transmitted helminthiases (STH) are still prevalent in Rwanda. We aimed to identify factors associated with the persistence of infection in selected sentinel sites that will be used to monitor the progress towards elimination. Infection prevalence and intensity were assessed using the Kato Katz (KK) and the Circulating Cathodic Antigen (CCA for schistosomiasis). Scooping and shedding were used to determine snail distribution and infectivity. Risk factors were collected through a structured questionnaire. Overall, the prevalence of STH and schistosomiasis on KK were 12.6% and 2.4% (higher on CCA) respectively. School aged children had significantly higher prevalence of infection except for Hookworm which was significantly higher among adults. Infection was significantly linked to the use of human excreta as fertilizers, the lack of clean water and poor quality toilets. Schistosomiasis distribution, higher in male participants compared to females, coincided with the geographical distribution of S. mansoni cercaria shedding. The findings highlight a significant contribution of agricultural practices and poor water/sanitation infrastructure on infection transmission, and call for a One Health (multi-sectoral collaboration) approach to enhance schistosomiasis and STH elimination in Rwanda. In addition, the correlation between infection and cercaria shedding emphasizes the potential benefits of snail surveillance in schistosomiasis hotspots.
