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

We have modeled the transition from acute to chronic pain in the rat. In this model (termed hyperalgesic priming) a chronic state develops after a prior inflammatory process or exposure to an inflammatory mediator, in which response to subsequent exposure to prostaglandin E2 (PGE2) is characterized by a protein kinase Cε-dependent marked prolongation of mechanical hyperalgesia. To assess the effect of priming on the function of the nociceptor, we have performed in vitro patch clamp and in vivo single-fiber electrophysiology studies using tumor necrosis factor α to induce priming. In vitro, the only change observed in nociceptors cultured from primed animals was a marked hyperpolarization in resting membrane potential (RMP); prolonged sensitization, measured at 60 minutes, could not be tested in vitro. However, complimentary with behavioral findings, in vivo baseline mechanical nociceptive threshold was significantly elevated compared to controls. Thirty minutes after injection of PGE2 into the peripheral receptive field, both primed and control nociceptors showed enhanced response to mechanical stimulation. However, 60 minutes after PGE2 administration, the response to mechanical stimulation was further increased in primed but not in control nociceptors. Thus, at the level of the primary afferent nociceptor, it is possible to demonstrate both altered function at baseline and prolonged PGE2-induced sensitization. Intrathecal antisense (AS) to Kv7.2, which contributes to RMP in sensory neurons, reversibly prevented the expression of priming in both behavioral and single-fiber electrophysiology experiments, implicating these channels in the expression of hyperalgesic priming.
