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

Inflammatory pain is associated with peripheral and central sensitization, but the underlying synaptic plasticity at the spinal cord level is poorly understood. Transient receptor potential (TRP) channels expressed at peripheral nerve endings, including TRP subtypes ankyrin 1 (TRPA1) and vanilloid 1 (TRPV1), can detect nociceptive stimuli. In this study, we determined the contribution of presynaptic TRPA1 and TRPV1 at the spinal cord level to regulating nociceptive drive in chronic inflammatory pain induced by complete Freund's adjuvant (CFA) in rats. CFA treatment caused a large increase in the frequency of spontaneous excitatory postsynaptic currents (EPSCs) in lamina I, but not lamina II outer zone, dorsal horn neurons. However, blocking NMDA receptors had no effect on spontaneous EPSCs in lamina I neurons of CFA-treated rats. Application of a specific TRPA1 antagonist, AM-0902, or of a specific TRPV1 antagonist, 5'-iodoresiniferatoxin, significantly attenuated the elevated frequency of spontaneous EPSCs and miniature EPSCs, the amplitude of monosynaptic EPSCs evoked from the dorsal root in lamina I neurons of CFA-treated rats. AM-0902 and 5'-iodoresiniferatoxin had no effect on evoked or miniature EPSCs in lamina I neurons of vehicle-treated rats. In addition, intrathecal injection of AM-0902 or 5'-iodoresiniferatoxin significantly reduced pain hypersensitivity in CFA-treated rats but had no effect on acute nociception in vehicle-treated rats. Therefore, unlike neuropathic pain, chronic inflammatory pain is associated with NMDA receptor-independent potentiation in glutamatergic drive to spinal lamina I neurons. Endogenous presynaptic TRPA1 and TRPV1 activity at the spinal level contributes to increased nociceptive input from primary sensory nerves to dorsal horn neurons in inflammatory pain.
