Strongyloidiasis as a Focal Household Cluster of Soil-Transmitted Helminthiasis in Rural Tropical Rainforest Southern Thailand: An Observational Study.
Article in Scientifica, 2026. 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
Background: In southern Thailand, characterized by high rainfall for 9 months each year (2340 mm annually), hookworm prevalence is consistently higher than that of Methods: We conducted a comparative observational study involving 346 of 418 village residents across eight designated subareas. Subareas 2, 4, 6, and 7 featured cluster settlements; Subareas 3 and 5 were diffuse low-income settings; and Subareas 1 and 8 represented mixed-density low-income areas. Each subarea contained at least one household lacking latrines. Stool samples were collected and analyzed using agar plate culture and the modified formalin-ether concentration technique to detect helminths. The spatial distributions of both infections were subsequently mapped and analyzed using spatial dispersion indices. Results: Of the eight subareas, six demonstrated a higher hookworm-to- Conclusion: In southern Thailand, strongyloidiasis appears to cluster within households, supporting the hypothesis of close-contact transmission, whereas hookworm infection is more widely distributed. These spatial differences suggest distinct, tailored targeting strategies are necessary for hookworm control and
