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
Nanoflow liquid chromatography coupled with a captive spray ionization time-of-flight tandem mass spectrometer (nLC/CSI-QTOF-MS/MS) was used in the structural determination of polar steroid compounds of starfish Lethasterias fusca. A total of 207 compounds including 106 asterosaponins, 81 glycosides of polyhydroxysteroids, and 14 polyhydroxylated steroids were detected and characterized by MS and MS/MS. Twenty compounds among them were unambiguously identified using authentic standard compounds, isolated earlier from this and other starfish species. The other compounds were tentatively characterized by accurate mass measurement and comparing retention times and characteristic MS/MS fragmentation patterns with reference standards. Moreover, fragmentation behaviors of a series of pure standards of starfish polar steroids and polyhydroxysteroid compounds detected in L. fusca have been extensively investigated and characteristic fragmentation pathways were described and used for the characterization of unknown compounds.
