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
Studies have shown the beneficial effects of musical instrument on memory and executive function in healthy aging. However, few studies investigated these long-term benefits. In this regard, the current study tracked a cohort of older adults (n = 53) over 4 years after they have initially participated in a musical instrument training program. Out of the initial sample, 13 of them voluntarily continued participating in the musical instrument training (continue group: 77.85 ± 4.30 years, 10 female, 3 male), while 19 of them discontinued their participation in the music program and instead engaged in other forms of leisure activities (stop group: age: 76.00 ± 5.44 years, 13 female, 6 male). At baseline, behavioral measures of verbal working memory (WM), verbal memory, and executive control were collected. In addition, participants completed a visual WM task (face n-back task) during fMRI scanning. Four years later, the same battery of tests was administered, with the addition of a digit n-back task to examine changes in verbal WM. Region-of-interest structural analyses focused on the striatum and cerebellum, based on previously reported intervention effects and the advantages observed in musicians. The continue group demonstrated better preservation of verbal WM performance (a composite score of Digit Span and Verbal Fluency tasks) and right putamen gray matter volume (GMV) over 4 years. During verbal WM processing, this group exhibited lower cerebellum-pons functional connectivity (FC), which significantly correlated with improved verbal WM performance. Moreover, the continue group also showed greater cerebellar activation during the digit task, increased intra-cerebellar FC, and decreased cerebellar-cortical FC during the face task. The combined evidence suggested enhanced cerebellar function and thus reduced reliance on other brain regions such as the cortical areas and brainstem for compensation. Taken together, these results suggested the musical instrument training effects in mitigating age-related decline in verbal WM and subcortical structure (putamen) and function (cerebellum). This study provides longitudinal evidence that initiating musical instrument training in older adulthood can counteract age-related cognitive and brain decline.
