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
Introduction: Adolescent binge drinking (BD) is a major public health concern, yet little is known about the neural markers that precede alcohol initiation. This longitudinal study examined whether magnetoencephalography (MEG) event-related fields (ERFs) recorded during inhibitory control predict later BD. Methods: Eighty-one alcoholnaïve adolescents initially completed a Go/No-Go task during MEG acquisition, alongside self-report measures of impulsivity, sensation seeking, and executive functioning. After two years, 44 participants remained eligible and were classified as controls (CN, n = 20; 10 females) or binge drinkers (BD, n = 24; 12 females) based on reported habits of alcohol consumption. Results: Behavioral analyses showed no group differences in accuracy in the inhibition task, impulsivity (BIS-11), or executive functioning (BRIEF-SR). The BD group reported higher sensation seeking (SSS-V). When studying electrophysiological activity, cluster-based permutation analyses revealed significant group differences in both the M200 (180-260ms) and M300 (310-510ms) components. In both cases, BD adolescents exhibited larger amplitudes, with sensors localized to left medial and dorsolateral prefrontal areas. These differences were moderate predictors in logistic regression models. Association between ERF and future alcohol use were not influenced by biological sex. Discussion: The results converge with prior evidence of left prefrontal hyperactivation in adolescent BD and developmental studies showing enhanced recruitment of control networks during adolescence. Findings support the hypothesis that atypical prefrontal executive engagement may represent a vulnerability profile that precedes alcohol use and may contribute to the emergence of BD.
