The role of mu opioid receptors on excitatory and inhibitory neurons in the rostral ventromedial medulla in neuropathic pain.
Article in bioRxiv : the preprint server for biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Descending projections from the brain to the spinal cord can regulate painful stimulus processing and are modulated by endogenous and exogenous opioids. We investigated the role of mu opioid receptors (MORs) in GABAergic vs. glutamatergic neurons of the rostral ventral medulla (RVM) in a mouse model of chronic neuropathic pain. We found that activating glutamatergic and GABAergic neurons in the RVM both result in antinociception at baseline, but glutamatergic neurons
