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
Objective: This study aimed to investigate the synaptic plasticity of the spinal dorsal horn regulated by the Piezo2/P2X7/MG signaling pathway and elucidate its role in the analgesic effects of massage in Cervical Spondylotic Radiculopathy (CSR), with the goal of identifying potential therapeutic targets for effective treatment. Methods: This experimental animal study included 40 Sprague-Dawley rats (180 ± 20 g), randomly divided into four groups (control, model, sham-operated, and massage; n=10 per group) after a one-week acclimation period. The CSR model was established by spinal canal insertion. Blood and spinal cord tissues were collected post-intervention. Mechanical pain threshold (MPT), 50% paw withdrawal threshold (50% PWT), immunofluorescence, Western blot, and qRT-PCR assays were employed to evaluate synaptic plasticity and pathway expression. Results: The massage group demonstrated significantly higher MPT and 50% PWT values compared to the model group post-intervention (P < 0.05). Downregulation of the Piezo2/P2X7/MG signaling pathway was observed in the massage group, correlating with a reduction in CSR progression, while upregulation in the model group promoted CSR (P < 0.05). Conclusion: The Piezo2/P2X7/MG signaling pathway regulates the synaptic plasticity of the spinal dorsal horn in CSR. These findings suggest that massage therapy can effectively alleviate CSR-associated pain by modulating this pathway, offering a potential noninvasive therapeutic approach.
