Intramolecularly Labeled Reference Standards of Sulfamethoxazole for Fragment-Specific Isotope Analysis by Electrospray Ionization Orbitrap Mass Spectrometry.
Article in Journal of the American Society for Mass Spectrometry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The widespread presence of pharmaceuticals, including antibiotics, in our aquatic environment raises important societal concerns. When studying their environmental fate, stable isotope analysis of nitrogen and carbon at natural abundance offers unique insight into source fingerprinting and degradation-associated kinetic isotope effects. Here, we synthesized compound-specific reference standards to enable electrospray ionization (ESI) Orbitrap mass spectrometry (MS) for fragment-specific carbon and nitrogen isotope analysis (Δδ
