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
This study presents an integrated chemical and biological assessment of Bellis annua methanolic extracts obtained through maceration (MAC), Soxhlet extraction (SOE), and ultrasound-assisted extraction (UAE). LC-electrospray ionization-mass spectrometry (ESI-MS)/MS profiling enabled the quantification of major phenolic compounds, including chlorogenic acid, hyperoside, hesperidin, and several hydroxycinnamic acids, revealing extraction-dependent variations in phenolic distribution. While total phenolic levels were comparable across methods, UAE yielded the highest flavonoid content and a broader enrichment of glycosylated flavonoids and hydroxycinnamates. Antioxidant capacity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical-scavenging assays, ferric reducing antioxidant power, cupric reducing antioxidant capacity, the phosphomolybdenum method, and a metal-chelation assay. All assays indicated notable activity of the extracts. UAE exhibited the strongest overall antioxidant performance as indicated by the Relative Antioxidant Capacity Index. Enzyme inhibition assays revealed method-specific differences: MAC showed the most pronounced acetylcholinesterase and α-amylase inhibition, whereas SOE demonstrated superior tyrosinase inhibition. Correlation analyses further indicated that flavonoid-rich extracts were strongly associated with radical-scavenging and metal-chelating activities, while specific phenolic acids contributed differentially to enzyme inhibition patterns. These findings highlight the influence of extraction technique on the chemical composition and multifunctional bioactivity of B. annua, supporting its potential as a promising natural source of phenolic-driven antioxidant and enzyme-inhibitory agents with relevance to pharmaceutical and nutraceutical applications.
