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
Interactions between per- and polyfluoroalkyl substances (PFASs) and small plastic particles (PPs) in the micro- and nanosize ranges raise serious concerns due to the possible joint harmful physiological effects of these emerging contaminants on the ecosystem. In this study, the adsorption of undecafluorohexanoic acid (UFHA), a C6 representative of PFASs, on amidine-functionalized polystyrene PP is investigated by using experimental and computer simulation methods. Electrophoretic light scattering measurements reveal that UFHA adsorbs strongly on oppositely charged PP leading to charge neutralization and overcharging at appropriate concentrations. Charged UFHA-PP adducts form stable colloids, while rapid aggregation was observed at the isoelectric point. Simulation results indicate that, at least at isoelectric conditions, a H-bond is formed between the oppositely charged groups of the PP and UFHA, providing an additional driving force, besides charge pairing, for this adsorption. This strong interaction results in an association of the PP chains and the majority of UFHA molecules, although some of the UFHA molecules can still stay isolated from these associates. It is found that the ionic strength applied in the solutions influences the adsorption process through charge screening of the PP surface, while it does not affect the charge neutralization conditions. Accordingly, the spatial distribution of the Na
