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

Transient receptor potential receptors (TRP) on primary afferent neurons respond to noxious and/or thermal stimuli. TRPV1 receptors can be activated by noxious heat, acid, capsaicin and resiniferatoxin, leading to burning pain or itch mediated by discharges in C polymodal and Adelta mechano-heat nociceptors and in central neurons, including spinothalamic tract (STT) cells. Central nociceptive transmission involves both non-NMDA and NMDA receptors, and inhibitory interneurons as well as projection neurons contribute to the neural interactions. Behavioral consequences of intradermal injection of capsaicin include pain, as well as primary and secondary hyperalgesia and allodynia. Primary hyperalgesia depends on sensitization of peripheral nociceptors, whereas, secondary hyperalgesia and allodynia result from sensitization of central nociceptive neurons, such as STT cells. Central sensitization is associated with enhanced responses to excitatory amino acids and decreased responses to inhibitory amino acids. The mechanism of the increase in responses to excitatory amino acids includes phosphorylation of NR1 subunits of NMDA receptors and GluR1 subunits of AMPA receptors. Central sensitization depends on activation of several protein kinases and other enzymes, such as nitric oxide synthase. This process is regulated by protein phosphatases. Central sensitization can be regarded as a spinal cord form of long-term potentiation.
