Clickable Glutathione-Based Identification of Cysteine Glutathionylation.
Article in Current protocols, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Clickable glutathione is a glutathione-derived chemical probe designed to identify and analyze protein S-glutathionylation, a major cysteine oxidation in redox signaling. An engineered glutathione synthetase mutant (GS M4) is used to synthesize clickable glutathione in cells or in vitro, which affords utility via click chemistry to detect, identify, and quantify glutathionylation on individual or global proteins in biochemical and mass spectrometric analyses. The clickable glutathione approach is valuable for the unequivocal identification of glutathionylated cysteines, among many reversible cysteine oxoforms, via the direct enrichment and detection of glutathionylated proteins or peptides. Clickable glutathione, in combination with GS M4, has demonstrated utility in the mass-spectrometry-based discovery and profiling of new proteins and cysteines for glutathionylation in cell lines in response to physiologic and oxidative stress. The approach is versatile and applicable to validating the glutathionylation of proteins and cysteines in other biochemical analysis beside mass spectrometry. Here, we describe the applications of clickable glutathione and provide detailed protocols for the identification, profiling, and detection of glutathionylated proteins and cysteines. © 2023 Wiley Periodicals LLC.
