Intermittent high-dose ethanol exposure increases ethanol preference in rats.

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
objectiveAlcohol use disorders have both high social and economic costs and are among the leading causes of preventable death in the United States. Understanding the factors that contribute to escalation of alcohol intake is important in developing effective treatments for this problem. This study further characterizes the effects of limited intermittent exposure to high levels of alcohol on the preference for alcohol consumption over other incentives.
methodFourteen male, Sprague-Dawley rats were trained to consume ethanol in a gelatin vehicle. They were then given free access to both ethanol gelatin and plain gelatin during daily choice periods interspersed with nonchoice periods (only plain gelatin access). After baseline ethanol preference was established, half of the rats were given eight injections of 3 g/kg ethanol during nonchoice periods (spread out over about 2 months), and the other half received saline injections. Ethanol preference was measured during subsequent choice periods.
resultsIntermittent ethanol injections increased ethanol preference from 21% (SEM = 2.3%) of their total gelatin consumption during the first choice period to 46.8% (SEM = 3.4%) during the third choice period. The saline-treated rats had no significant change in ethanol preference. In addition, the ethanol-treated rats exhibited higher ethanol intake than saline-treated rats when ethanol gelatin was the only choice available.
conclusionsThe results indicate that intermittent exposure to sedative doses of ethanol leads to an increased ethanol preference in rats. This suggests that occasional high-dose alcohol exposure could be an important contributor to the development of enhanced ethanol intake, which may affect the incidence of chronic alcoholism.
