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
Understanding organ-specific phytochemical variation is essential for elucidating how chemical diversity shapes biological activity in narrowly distributed Apiaceae. This study provides the first comprehensive evaluation of the nonvolatile phytochemical composition, antioxidant potential, and enzyme inhibitory properties of ethanol extracts obtained from the leaves, flowers, stems, and roots of Chaerophyllum aksekiense. Total phenolic and flavonoid levels differed markedly among organs, with leaves exhibiting the highest phenolic content and flowers the greatest flavonoid accumulation. LC-ESI-MS/MS analysis revealed distinct distribution patterns of key compounds, including hyperoside, gallic acid, caffeic acid, and hydroxybenzoic acids. Antioxidant activity differed across assays, with leaf extracts demonstrating the strongest electron-transfer and radical-scavenging capacities in phosphomolybdenum, CUPRAC, FRAP, DPPH, and ABTS assays, reflected by the highest relative antioxidant capacity index (RACI) score. Stem extracts were the most effective metal chelators. Enzyme inhibition activities were similarly differentiated; leaves and roots exhibited the strongest cholinesterase inhibition, roots were most active against α-amylase, and leaves against α-glucosidase. Correlation analysis highlighted gallic and caffeic acids as major contributors to both antioxidant and enzyme-modulatory outcomes. Collectively, these findings emphasize that C. aksekiense displays pronounced organ-specific phytochemical organization that drives its diverse bioactivities, and they identify key organs and compounds with potential value for future mechanistic and application-oriented studies.
