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
Per- and polyfluoroalkyl substances (PFAS) are regarded as persistent environmental pollutants with the potential to exert deleterious effects on human health, particularly in children, who are highly susceptible to the effects of environmental exposures. This study presents the development and validation of a sensitive LC-MS/MS method for the simultaneous analysis of 39 PFAS compounds in soil samples. Method performance characteristics that were examined through a fully validated protocol including linearity, precision, detectability, and trueness proved its fitness for environmental monitoring. This method was subsequently employed in an analysis of 67 soil samples obtained from playgrounds in Attica, Greece. The results indicated the presence of PFAS in all of the samples analyzed, with PFPeA, PFOA, PFDA, PFBS, and PFOS being the most prevalent compounds in terms of concentration levels. Risk assessment of PFAS occurrence in these samples showed that the risk quotient for PFOS exceeded 1 in 20% of the studied samples, indicating a potential risk of exposure for children. Concentrations varied depending on urban activities and potential pollution sources. This study provides a reliable tool for the systematic monitoring of PFAS in soil and emphasizes the importance of ongoing monitoring and risk assessment in areas where children play.
