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
Nardostachys jatamansi is an endangered aromatic plant that produces a chemically complex and diverse array of secondary metabolites. In this study, we aimed to comprehensively characterize the chemical diversity of N. jatamansi by liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based metabolite annotation. A metabolite annotation workflow combining feature detection, library matching, MetFrag-based in silico fragmentation, SIRIUS fragmentation tree analysis, manual MS/MS interpretation, molecular networking, chemical classification, and structural validation of selected compounds was applied to methanolic extracts of N. jatamansi. Using this integrated strategy, 111 peaks were structurally annotated, and an additional 13 peaks were assigned to tentative structural level annotations based on MS/MS fragment similarity in a molecular network, giving a total of 124 peaks classified at the chemical structural level. The annotated metabolites mainly comprised iridoids, lignans, sesquiterpenoids, sesquiterpenoid hybrids, monoterpenoids, flavonoids, and other constituents such as fatty acids and phenylpropanoids, revealing the remarkable chemical diversity of N. jatamansi. The annotation performance of each metabolite annotation platform was systematically compared in terms of coverage, efficiency, and chemical class level specificity, revealing that these platforms provided complementary annotations whose combined use with molecular networking greatly enhanced metabolite coverage and structural interpretation. This integrated LC-MS/MS and multi-platform workflow extends current knowledge of the chemical diversity of N. jatamansi.
