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
backgroundWhile Pisum sativum L. is primarily valued for its seeds, its aerial parts have received limited attention. This study aimed to explore the anti-inflammatory and wound-healing potential of pea leaves and stems to promote their broader utilization.
methodsA bioassay-guided strategy was applied to various fractions of P. sativum aerial parts to evaluate their immunomodulatory activity using leukocyte accumulation assay. Active fractions were further assessed in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages for their effects on TNF-α gene expression, interleukin-6 (IL-6), and nitric oxide production. The bioactive petrol eum ether (PSP) and ethyl acetate (PSE) fractions were further analyzed through GC-MS analysis, LC-MS/MS analysis, and chromatographic purification. The purified compounds were evaluated in human monocytes for their effects on IL-6 secretion and intracellular reactive oxygen species (ROS) production, and in HaCaT keratinocytes for their wound-healing potential using a scratch assay. Network pharmacology and molecular docking analyses were employed as in-silico tools to predict key targets and mechanistic pathways.
resultsBoth PSE and PSP fractions promoted leukocyte accumulation and significantly decreased TNF-α expression, IL-6, and nitric oxide production levels. LC-MS/MS analysis of PSE revealed 42 compounds, predominantly flavonoids and phenolics, potentially accounting for its anti-inflammatory activity. Among seven isolated constituents, pisatin exhibited superior activity by markedly suppressing IL-6 and ROS in human monocytes and promoting 73% wound closure in keratinocytes within 48 h.
conclusionsThese findings establish P. sativum aerial parts as an accessible and valuable source of natural products with potential wound-healing activity, supporting the sustainable use of these underexploited agricultural materials.
