1 · What the graph read from it

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.

2 · The registry

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

Neuropathic pain, the most debilitating of all clinical pain syndromes, may be a consequence of trauma, infection or pathology from diseases that affect peripheral nerves. Here we provide a framework for understanding the spinal mechanisms of neuropathic pain as distinct from those of acute pain or inflammatory pain. Recent work suggests that a specific microglia response phenotype characterized by de novo expression of the purinergic receptor P2X4 is critical for the pathogenesis of pain hypersensitivity caused by injury to peripheral nerves. Stimulating P2X4 receptors initiates a core pain signaling pathway mediated by release of brain-derived neurotrophic factor, which produces a disinhibitory increase in intracellular chloride in nociceptive (pain-transmitting) neurons in the spinal dorsal horn. The changes caused by signaling from P2X4R(+) microglia to nociceptive transmission neurons may account for the main symptoms of neuropathic pain in humans, and they point to specific interventions to alleviate this debilitating condition.
