Structural elucidation and isomeric differentiation/quantitation of monophosphorylated phosphoinositides using gas-phase ion/ion reactions and dissociation kinetics.
Article in The Analyst, 2022. 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
Phosphoinositides, phosphorylated derivatives of phosphatidylinositols, are essential signaling phospholipids in all mammalian cellular membranes. With three known phosphorylated derivatives of phosphatidylinositols at the 3-, 4-, and 5-positions along the myo-inositol ring, various fatty acyl chain lengths, and varying degrees of unsaturation, numerous isomers can be present. It is challenging for shotgun-MS to accurately identify and characterize phosphoinositides and their isomers using the most readily available precursor ion types. To overcome this challenge, novel gas-phase ion/ion chemistry was used to expand the range of precursor ion-types for subsequent structural characterization of phosphoinositides using shot-gun tandem mass spectrometry. The degree of phosphorylation and fatty acyl sum composition are readily obtained by ion-trap CID of deprotonated phosphoinositides. Carbon-carbon double bond position of the fatty acyl chains can be localized
