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: Shoulder injuries are highly prevalent in overhead sports such as water polo due to repetitive high-intensity throwing demands. While structural pathologies have been widely studied, there is a lack of evidence regarding the role of myofascial dysfunction in this athletic population. Hypothesis/Purpose: This study aims to analyze the relationship between myofascial dysfunction in the shoulder musculature and self-perceived functional capacity in competitive water polo players. Design: Observational cohort. Methods: Male water polo players from youth and senior categories of two clubs in Madrid (Spain) were recruited for participation in this study. A clinical evaluation of myofascial dysfunction was performed through manual assessment of myofascial trigger points (MTrPs) using a composite score (0-6) based on the presence of six diagnostic criteria and completion of the Kerlan-Jobe Orthopaedic Clinic Shoulder and Elbow Score questionnaire were performed. Spearman correlation analysis and hierarchical multiple regression were performed to examine the association between MTrPs and shoulder function. Results: A total of 33 water polo players aged 18.30 ± 2.82 years were included. Significant moderate negative correlations were found between myofascial trigger point scores and the KJOC score for the infraspinatus (r = -0.413, p = 0.017), subscapularis (r = -0.377, p = 0.030), and anterior (r = -0.580, p < 0.001), middle (r = -0.480, p = 0.005), and posterior deltoid (r = -0.534, p = 0.001). Conclusion: The findings suggest that myofascial dysfunction significantly negatively impacts shoulder function and performance in water polo athletes. Level of Evidence: Level 3.
