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 recently implicated mitochondrial mechanisms in models of neuropathic and inflammatory pain, in some of which a role of protein kinase Cepsilon (PKCepsilon) has also been implicated. Since mitochondria contain several proteins that are targets of PKCepsilon, we evaluated the role of mitochondrial mechanisms in mechanical hyperalgesia induced by proinflammatory cytokines that induce PKCepsilon-dependent nociceptor sensitization, and by a direct activator of PKCepsilon (psiepsilonRACK), in the rat. Prostaglandin E(2) (PGE(2))-induced hyperalgesia is short lived in naïve rats, while it is prolonged in psiepsilonRACK pre-treated rats, a phenomenon referred to as priming. Inhibitors of two closely related mitochondrial functions, electron transport (complexes I-V) and oxidative stress (reactive oxygen species), attenuated mechanical hyperalgesia induced by intradermal injection of psiepsilonRACK. In marked contrast, in a PKCepsilon-dependent form of mechanical hyperalgesia induced by prostaglandin E(2) (PGE(2)), inhibitors of mitochondrial function failed to attenuate hyperalgesia. These studies support the suggestion that at least two downstream signaling pathways can mediate the hyperalgesia induced by activating PKCepsilon.
