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

rationaleAlcohol-dependent animals display enhanced stress responsivity, reward thresholds, and alcohol self-administration during alcohol withdrawal, and some of these aspects of alcohol dependence may be mediated by activation of brain norepinephrine (NE) systems.

objectivesThis study examined the effects of propranolol, a β-adrenoceptor antagonist, on operant alcohol-reinforced responding by alcohol-dependent and non-dependent rats.

methodsAdult male Wistar rats were trained to respond for alcohol in an operant conditioning paradigm on fixed-ratio-1 (FR-1) and progressive ratio (PR) reinforcement schedules. Rats were either made dependent on alcohol via chronic intermittent (14 h ON/10 h OFF) alcohol vapor inhalation or were not exposed to alcohol vapor. Rats were tested for the effects of propranolol (0-10 mg/kg) or nadolol (0-20 mg/kg) on operant alcohol-reinforced responding at the time point corresponding to 6-8 h withdrawal in dependent animals.

resultsAll doses of propranolol suppressed FR-1 operant alcohol-reinforced responding in alcohol-dependent rats, but only the highest dose suppressed FR-1 responding by controls. No dose of propranolol affected water responding. Nadolol did not affect operant behavior. Propranolol suppressed PR operant alcohol-reinforced responding across groups, an effect attributable to significant suppression of alcohol responding at the highest dose.

conclusionsFollowing development of alcohol dependence, rats exhibit hypersensitivity to the suppressive effects of propranolol on operant alcohol-reinforced responding. This effect is mediated by central actions of the drug, is not attributable to motor effects, and may reflect activation of brain NE systems that contributes to withdrawal-induced negative emotional states and drives alcohol drinking in the dependent organism.
