Geospatial Analysis of Hymenolepis (Rodentolepis) nana Infection Transmission in Schools among Children in Cusco, Peru.
Article in The American journal of tropical medicine and hygiene, 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
Hymenolepis nana is an emergent parasitosis, and the role of schools in infection transmission is unclear. Data from a cross-sectional study evaluating children for H. nana infection in schools in three districts of Anta province in Peru were analyzed. Geospatial information from the children's residence and school was obtained. A total of 2,961 children were included from 51 different schools. The median age was 9.6 years old (interquartile range [IQR]: 6.8-12.4), 1,479 (50%) were female, and the median H. nana prevalence per school was 15% (IQR: 3.61-24.20). Regression analysis demonstrated that those living in Ancahuasi and Zurite and those with higher poverty score and higher residence altitude were more likely to reside on a hot spot than a cold spot based on residence distribution, whereas being of school age was protective. Children living in low-risk areas (nonhot spots) who were attending schools with higher prevalence of H. nana (≥15%) were less likely to reside in Ancahuasi or Zurite than in Anta, had lower paternal education, and were older than 6 years of age. Our study shows that schools have a role in infection transmission among children in the highlands of Peru.
