Unravel the in-Source Fragmentation Patterns of Per- and Polyfluoroalkyl Substances during Analysis by LC-ESI-HRMS.
Article in Environmental science & technology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
In-source fragmentation (ISF) was inevitable during electrospray ionization (ESI) of per- and polyfluoroalkyl substances (PFAS) when analyzed by liquid chromatography coupled with mass spectrometry (LC-MS), resulting in reduced response of molecular ions and misannotation of MS features. Herein, we analyzed 82 PFAS across 12 classes to systematically identify the structures with ISF potentials and reveal the fragmentation pathways. We found up to 100% ISF for 38 PFAS in six classes, which all contain the carboxylate (CO
