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

rationaleThe activation of cannabinoid 2 receptors (CB2R) attenuates chronic pain, but the role played by carbon monoxide synthesized by the inducible heme oxygenase 1 (HO-1) on the anti-nociceptive effects produced by a selective CB2R agonist, JWH-015, during painful diabetic neuropathy remains unknown. OBJECTIVES AND

methodsIn streptozotocin (STZ)-induced diabetic mice, the anti-allodynic and anti-hyperalgesic effects of the subcutaneous administration of JWH-015 alone or combined with the intraperitoneal administration of a carbon monoxide-releasing molecule (tricarbonyldichlororuthenium(II) dimer (CORM-2)) or an HO-1 inducer compound (cobalt protoporphyrin IX (CoPP)) at 10 mg/kg were evaluated. Reversion of JWH-015 anti-nociceptive effects by the administration of an HO-1 inhibitor (tin protoporphyrin IX (SnPP)) and a CB2R antagonist (AM630) was also evaluated. Furthermore, the protein levels of HO-1, neuronal nitric oxide synthase (NOS1), and CB2R in diabetic mice treated with CORM-2 and CoPP alone or combined with JWH-015 were also assessed.

resultsThe administration of JWH-015 dose dependently inhibited hypersensitivity induced by diabetes. The effects of JWH-015 were enhanced by their coadministration with CORM-2 or CoPP and reversed by SnPP or AM630. The increased protein levels of HO-1 induced by CORM-2 and CoPP treatments were further enhanced in JWH-015-treated mice. All treatments similarly enhanced the peripheral expression of CB2R and avoided the spinal cord over-expression of NOS1 induced by diabetes.

conclusionsThe activation of HO-1 enhanced the anti-nociceptive effects of JWH-015 in diabetic mice, suggesting that coadministration of JWH-015 with CORM-2 or CoPP might be an interesting approach for the treatment of painful diabetic neuropathy in mice.
