Mechanical Acupuncture at ST36 Attenuates Inflammatory Pain Involving TRPV1 Signaling in Mice.
Article in International journal of molecular sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
We recently developed a mechanical acupuncture instrument (MAI) that applies mechanical stimulation to acupuncture points in effectively treating hypertension and addiction in animal models. However, its analgesic effect on inflammatory pain remains unclear. Here, we aimed to determine the optimal duration of MAI treatment at any given acupuncture point to improve analgesic effects. Adult male ICR mice (20-25 g, 6 weeks old, n = 6 per group) were used to evaluate whether MAI administration or TRPV1 (transient receptor potential vanilloid 1) inhibition had analgesic effects. Then, we investigated whether it affected TRPV1 expression and glial cells in the spinal cord of mice. The capsaicin test was used to identify the most effective acupoints and optimal treatment times for MAI. Additionally, we induced inflammatory pain in mice by administering a 2% carrageenan via intraplantar injection. To assess the analgesic effects of MAI treatment and TRPV1 inhibition, we evaluated pain-related behavior using von Frey filaments and a thermal stimulator applied to the hind paw. MAI treatment significantly suppressed pain-related behaviors. In particular, paw-licking duration was markedly reduced in the group treated with MAI for 60 s at ST36 compared to the capsaicin-treated group (
