Pesticide Contamination in the Hair of Children From Colonia San Juan, a Rural Community in Paraguay.

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
Chronic exposure to pesticides can cause carcinogenic, reproductive, neurological, and endocrine-disrupting effects. Hair analysis is a valuable biomonitoring tool to assess human exposure to pesticides. We determined the presence of pesticides, their metabolites, and other environmental pollutants in the hair of children in an agricultural area of Paraguay. We analyzed 152 pesticides and environmental chemicals in hair samples from 51 children (2-14 years, mean ± SD = 8.5 ± 3.3 years) living in Colonia San Juan, a rural community in Paraguay. The locality is surrounded by soybean crops, and the community engages primarily in family farming. Eighty of the 152 compounds (52.6%) were detected. Each child's sample contained an average of 55 ± 3.7 compounds (range 48-65), including organophosphates, pyrethroids, neonicotinoids, fungicides, herbicides, and endocrine disruptors such as bisphenol A and bisphenol S. Thirty-seven compounds were present in all samples. Children in this rural community are simultaneously exposed to numerous pesticides and pollutants, highlighting the urgent need for stricter environmental protections and preventive health measures.
