1 · What the graph read from it

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.

2 · The registry

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

Accurate quantification of per- and polyfluoroalkyl substances (PFAS) in environmental matrices is crucial for reliable exposure assessment but remains challenging owing to low concentrations and matrix-induced variability. In this study, three calibration approaches, external standard (ES), internal standard (IS), and isotope dilution mass spectrometry (IDMS), were systematically evaluated for the determination of perfluorohexanesulfonic acid (PFHxS), perfluorooctanesulfonic acid (PFOS), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) in fortified tap water and fortified soil. Linearity of calibration curves was assessed across five concentration levels for each analyte. IDMS consistently demonstrated the highest linearity (coefficient of determination R
