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
backgroundBinge drinking, defined as episodic alcohol intake reaching intoxication, is prevalent among young adults and linked to impaired cognitive control and risk for alcohol use disorder (AUD). Even though executive deficits contribute to addiction, evidence on their alterations in young adult binge drinkers (BDs) as a function of biological sex remains limited. This study examined cognitive and motor aspects of decision making as reflected in event-related theta and beta oscillations, respectively. The executive neurobehavioral markers were analyzed in conjunction with alcohol-related and other self-reported variables and cognitive functions in BDs versus light drinkers (LDs) of both sexes.
methodsSixty-eight participants (34 BDs, 34 LDs, 50% women) completed a modified Stroop task. Electroencephalography (EEG) signals were analyzed in the time-frequency domain with Morlet wavelets. Behavioral performance and event-related theta (4-7 Hz) and beta (15-25 Hz) power were compared across levels of conflict, drinking groups, and sex.
resultsBDs exhibited longer reaction times on high-conflict trials, reflecting compensatory slowing during cognitive interference. Lower conflict-induced theta power in BDs than in LDs was evident primarily among women. It was associated with greater alcohol intake and it mediated the impact of binge drinking on degraded task performance among BD women. In contrast, event-related beta desynchronization during response preparation was attenuated and delayed only in BD men, which was partially mediated by impulsivity.
conclusionsThe observed links between binge drinking and dysregulated cognitive and motor control processes were interpreted in regard to sex-specific neural alterations. Weaker engagement of cognitive control in BD women may be reflected in an impaired capacity to optimize decisions in challenging situations. Beta decrease during response preparation was especially attenuated in more impulsive BD men, which may contribute to their inability to refrain from risky behaviors. These findings highlight the need to consider biological sex in alcohol-related neurocognitive research.
