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

Metastatic and primary bone cancers are usually accompanied by severe pain that is difficult to manage. In light of the adverse side effects of opioids, manipulation of the endocannabinoid system may provide an effective alternative for the treatment of cancer pain. The present study determined that a local, peripheral increase in the endocannabinoid 2-arachidonoyl glycerol (2-AG) reduced mechanical hyperalgesia evoked by the growth of a fibrosarcoma tumor in and around the calcaneous bone. Intraplantar (ipl) injection of 2-AG attenuated hyperalgesia (ED(50) of 8.2 μg) by activation of peripheral CB2 but not CB1 receptors and had an efficacy comparable to that of morphine. JZL184 (10 μg, ipl), an inhibitor of 2-AG degradation, increased the local level of 2-AG and mimicked the anti-hyperalgesic effect of 2-AG, also through a CB2 receptor-dependent mechanism. These effects were accompanied by an increase in CB2 receptor protein in plantar skin of the tumor-bearing paw as well as an increase in the level of 2-AG. In naïve mice, intraplantar administration of the CB2 receptor antagonist AM630 did not alter responses to mechanical stimuli demonstrating that peripheral CB2 receptor tone does not modulate mechanical sensitivity. These data extend our previous findings with anandamide in the same model and suggest that the peripheral endocannabinoid system is a promising target for the management of cancer pain.
