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

rationaleAs contamination of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in the environment becomes better understood, it is increasingly important to develop forensic tools capable of tracing contamination to emission sources. Isotopic methods have been previously inaccessible for PFAS due to limitations of the instrumentation, but high-pressure liquid chromatography (HPLC) coupled to Orbitrap mass spectrometry (Orbitrap MS) through electrospray ionization (ESI) allows measurement of the isotopic composition of individual PFAS compounds, such as perfluorooctanoic acid (PFOA).

methodsSix separate supplier-procured powders of PFOA were analyzed for their δ

resultsThe method presented replicated, within error, the δ

conclusionsWe developed a method capable of measuring the carbon isotopic composition of PFOA, using HPLC-Orbitrap MS, with high precision and accuracy. This will allow future research to expand analytical capabilities for additional isotopologues of PFOA and other PFAS compounds.
