Context-Dependent Extinction and Return of Pavlovian Alcohol-Seeking Behavior in Male and Female Rats.
Article in Alcohol, clinical & experimental research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEnvironmental cues can become conditioned stimuli when associated with alcohol consumption, facilitating alcohol-seeking behavior and increasing relapse risk. Extinguishing alcohol-seeking behavior may reduce cue-induced responses; however, conditioned responding often occurs when the cue is presented in a different context than the one where the behavior was extinguished. Although prior research suggests that males generally show stronger context-dependent return of conditioned appetitive and fear responses, it is not known whether this sex difference extends to conditioned responses to alcohol-associated cues.
methodsAfter a 5-week alcohol induction period, adult male and female Long-Evans rats underwent Pavlovian conditioning in Context A, where a 15% unsweetened alcohol solution was paired with a light cue. Extinction sessions were conducted in a distinct Context B in the absence of alcohol, followed by a test session in Context B (LTM) and then in Context A.
resultsBoth sexes successfully extinguished alcohol-seeking behavior in Context B but exhibited robust alcohol-seeking behavior when reintroduced to the alcohol-associated context, Context A. No significant sex differences were observed in the magnitude of reemerged conditioned responding.
conclusionsThese findings suggest that changes of context induce alcohol-seeking behavior to return similarly in male and female rats, indicating that sex-independent mechanisms may underlie contextual relapse processes.
