Antinociceptive effect of Equisetum arvense extract on the stomatitis hamster model.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Recurrent aphthous stomatitis leads to ulcers that cause severe pain, which is a substantial burden on patients. Equisetum arvense extract (EA) is a crude drug that promotes wound healing of mucous membranes caused by perineal incision during childbirth and alleviates pain. Here, we elucidated the effects of EA on wound healing and pain in a stomatitis hamster model. After stomatitis induction, two different EA doses were continuously applied to the wound area through the intramucosal injection of acetic acid into the cheek pouch (stomatitis/100*EA group and stomatitis/EA group). The body weight and wound area were measured over time, and histological evaluation was performed after stomatitis induction. The wound area was harvested 10 h after stomatitis induction, and gene expression associated with pain and inflammation was analyzed using qPCR. The dorsal root ganglia of the rat spinal cord were isolated, dispersed, and cultured to examine the inhibitory effect of EA on the K+-evoked release of neurotransmitter substance P. In the stomatitis/100*EA group, a significant reduction in wound size was observed compared with the stomatitis/physiological saline (PS) group, and the weight gain rate was considerably higher. The stomatitis/EA group revealed similar histological changes in the wound and wound size as the stomatitis/PS group; however, the weight gain rate was considerably higher on day 7. The stomatitis/EA group suppressed the expression of inflammatory cytokine mRNA, such as Tnf-α and Il-6, and Cox-2 mRNA in the wound area compared with the stomatitis/PS group. EA treatment reduced the upregulated substance P release from the dorsal root ganglia following high-concentration K+ stimulation. EA alleviates pain in a stomatitis model by suppressing inflammatory cytokine expression in the wound area and substance P release from primary sensory neurons. Therefore, using oral care products containing EA is expected to suppress stomatitis pain.
