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

backgroundNeuropathic pain is a debilitating condition with no adequate therapy. The health benefits of omega-3 fatty acids are established, however, the role of docosahexaenoic acid (DHA) in limiting pain has only recently been described and the mechanisms of this action remain unknown. DHA is metabolized into epoxydocosapentanoic acids (EDPs) via cytochrome P450 (CYP450) enzymes which are substrates for the soluble epoxide hydrolase (sEH) enzyme. Here, we tested several hypotheses; first, that the antinociceptive action of DHA is mediated by the EDPs. Second, based on evidence that DHA and CYP450 metabolites elicit analgesia through opioid signalling, we investigated this as a possible mechanism of action. Third, we tested whether the analgesia mediated by epoxy fatty acids had similar rewarding effects as opioid analgesics.

methodsWe tested diabetic neuropathic wild-type and sEH null mice in a conditioned place preference assay for their response to EDPs, sEHI and antagonism of these treatments with naloxone, a mu-opioid receptor antagonist.

resultsThe EDPs and sEH inhibitors were efficacious against chronic pain, and naloxone antagonized the action of both EDPs and sEH inhibitors. Despite this antagonism, the sEH inhibitors lacked reward side effects differing from opioids.

conclusionsThe EpFA are analgesic against chronic pain differing from opioids which have limited efficacy in chronic conditions. SIGNIFICANCE: EDPs and sEHI mediate analgesia in modelled chronic pain and this analgesia is blocked by naloxone. However, unlike opioids, sEHI are highly effective in neuropathic pain models and importantly lack rewarding side effects.
