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

background and purposeIn anaesthetized spontaneously hypertensive rats (SHR), there is evidence for up-regulation of cannabinoid (CB1) receptors: antagonism of CB1 receptors causes a rise in blood pressure, and administration of the endocannabinoid, anandamide, or inhibition of anandamide degradation causes hypotension. These findings have led to the suggestion that the endocannabinoid system may be a therapeutic target in hypertension. However, since the cardiovascular responses to cannabinoids are substantially influenced by anaesthesia, the purpose of this study was to assess regional haemodynamic responses to cannabinoid receptor stimulation and inhibition in conscious SHR. EXPERIMENTAL APPROACH: Cardiovascular responses to i.v. administration of anandamide, the cannabinoid receptor agonist, WIN 55212-2, and the CB(1) receptor antagonist, AM 251, were measured in male SHR, Wistar Kyoto rats and outbred Wistar rats, chronically instrumented for recording renal, mesenteric and hindquarters haemodynamics in the conscious, freely-moving state. KEY

resultsHypotensive responses to anandamide and WIN 55212-2 only occurred in SHR, but these were relatively modest and not associated with CB1 receptor-mediated vasodilatation. In SHR only, anandamide caused bradycardia, which was inhibited by AM 251. Furthermore, a pressor response to CB1 receptor antagonism occurred only in SHR, but was not associated with vasoconstriction. Moreover, there was some evidence for CB1 receptor-mediated vasoconstrictor actions of anandamide in SHR, which was not seen in the normotensive strains. CONCLUSIONS AND IMPLICATIONS: The results are consistent with activation of CB1 receptors in SHR by endogenous ligands exerting an antihypertensive effect, but the findings do not indicate enhanced CB1 receptor-mediated vasodilator mechanisms in SHR.
