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
Silver nanoparticles (AgNPs) are increasingly recognized as active elicitors capable of modulating plant growth and metabolism. This study evaluated the effects of AgNPs (1.0-50.0 mg/L) on in vitro shoot cultures of Clinopodium nepeta subsp. spruneri (Boiss.) Bartolucci & F. Conti (Lamiaceae). AgNP exposure significantly reduced shoot length, leaf and node numbers, and completely suppressed root formation, while biomass accumulation increased in a concentration-dependent manner. High-performance liquid chromatography (HPLC) identified rosmarinic acid (RA) as the major phenolic, with levels rising 2.5- to 4.5-fold in treated shoots compared with control and wild plants. The maximum RA content, total phenolic concentration, antioxidant activity (DPPH and FRAP), and acetylcholinesterase (AChE) inhibition were observed at 20.0 mg/L AgNP. In contrast, the highest flavonoid content was recorded in the wild plant. Gas chromatography-mass spectrometry (GC-MS) analysis revealed that isoeugenol dominated in AgNP-treated cultures, while menthalactone was the principal constituent in both control and wild samples. These findings demonstrate that AgNPs substantially alter the metabolic profile of C. nepeta subsp. spruneri, highlighting their potential as elicitors for enhancing phenolic accumulation, antioxidant activity, and enzyme inhibition under in vitro conditions.
