Effects of A₂A adenosine receptor blockade or stimulation on alcohol intake in alcohol-preferring rats.
Article in Psychopharmacology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers.
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.
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
rationaleA(2A) adenosine receptors (A(2A)ARs) have been proposed to be involved in drug addiction; however, preclinical studies about the effects of A(2A)AR ligands on alcohol consumption have provided inconsistent results.
objectivesThe present study evaluated the effect of intraperitoneal injections of the A(2A)AR antagonist ANR 94, and the A(2A)AR agonists CGS 21680 and VT 7 on voluntary drinking and operant self-administration of 10% ethanol in Marchigian Sardinian alcohol-preferring (msP) rats.
resultsVoluntary ethanol drinking was increased by ANR 94 in acute and subchronic experiments, while it was reduced by A(2A)AR agonists. The effect of CGS 21680 was abolished by a low dose of ANR 94, confirming its mediation by A(2A)ARs. Ethanol self-administration was reduced by CGS 21680 and VT 7, while ANR 94 slightly but significantly increased it. Blood alcohol levels were not modified by A(2A)AR agonists, indicating that their effect is not related to ethanol pharmacokinetics. The effect of VT 7 on ethanol drinking was behaviourally selective; ethanol and food intake were reduced, but water intake was increased, and total fluid intake was not different from that of controls. Moreover, VT 7 did not affect locomotor activity. CGS 21680 (0.1 mg/kg) did not modify total fluid intake, but 0.2 and 0.3 mg/kg reduced total fluid intake and locomotor activity.
conclusionThese results provide evidence that A(2A)AR agonists reduce ethanol consumption in msP rats, which represent an animal model of alcohol abuse related to stress, anxiety and depression. A(2A)ARs may represent a potential target for treatment of alcohol abuse.
