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: A balanced psychological wellbeing and healthy lifestyle-which includes regular physical activity and the prevention of alcohol and tobacco use-are relevant for neuropsychological functioning. We aimed to analyze the association between adolescent psychological wellbeing, physical activity, and ever having used alcohol and tobacco with neuropsychological principal components (PC). Method: This cross-sectional research used the baseline data from a sample of 523 healthy adolescents enrolled in the Walnuts Smart Snack Dietary Intervention Trial from Barcelona. We performed principal components analysis (PCA) to determine neuropsychological PC using working memory, fluid intelligence, emotional recognition, risky decision-making and attention deficit hyperactivity disorder (ADHD) symptoms. Multiple linear regression was used to analyze the relationship between psychological wellbeing, physical activity, and ever used alcohol and tobacco with neuropsychological PC. Regression models were adjusted by child sex, age, maternal education, and socioeconomic status. Results: Two neuropsychological PC, "ADHD symptoms" and "hot executive function," were identified in PCA analyses (eigenvalues > 1.0). Psychological wellbeing showed an inverse association with the "ADHD symptoms" PC (β Conclusion: Our main results suggest that less psychological wellbeing, as well as ever having used alcohol or tobacco, was associated with "ADHD symptoms" PC. Physical activity might have a direct association with "hot executive functions" PC in a healthy adolescent sample.
