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
Background: It is widely recognized that sports, dance, and other structured extracurricular activities can positively influence children's executive function. However, previous research has not thoroughly examined whether participation in a diverse range of activities aimed at acquiring new skills affects working memory development in children. Objective: To investigate the impact of the quantity of extracurricular activities on the development of working memory among 5-7-year-old children. Design: Longitudinal data on working memory development were collected from children aged 5 to 7 years (N = 101). Three assessments of verbal and visual working memory were conducted at ages 5, 6, and 7 years. Information on children's participating in extracurricular activities was obtained through parental surveys. Results: The findings indicate that the number of extracurricular activities in which children participated has a significant positive effect on verbal working memory, with children engaged in multiple types of activities demonstrating a superior ability to retain and reproduce verbal information. Conversely, visual-spatial working memory did not show statistically significant differences based on the number of extracurricular activities. Conclusion: These results suggest that increasing access to extracurricular activities may foster verbal working memory, which is an important predictor of subsequent academic success and socialization.
