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
Objectives: This study aims to determine whether sarcopenia is associated with the presence, severity, or type of rotator cuff tears in patients with rotator cuff syndrome. It also assesses how the degree of shoulder pain and functional disability relate to the existence of sarcopenia in patients with rotator cuff syndrome, as well as examines the impact of the patients' clinical characteristics and physical activity levels on sarcopenia. Patients and methods: In this cross-sectional study conducted between October 2024 and October 2025, 130 patients with shoulder pain lasting at least three months were assessed, of whom 124 (25 males, 99 females; mean age: 60.4±10.3 years; range: 40 to 85 years) met the study criteria and were included in the analysis. Of these, 69 were sarcopenic, 15 presarcopenic, and 40 non-sarcopenic. Sarcopenia was evaluated using the ISarcoPRM diagnostic algorithm, which includes gait speed, handgrip strength, chair stand test, and ultrasonographic measurement of anterior thigh muscle thickness. Shoulder magnetic resonance imaging scans were assessed for the presence, type, and severity of rotator cuff tears, focusing particularly on supraspinatus tears, tendinosis, muscle atrophy (tangent sign), and impingement. Results: Comparative analysis of the three groups revealed no statistically significant differences in supraspinatus tear, supraspinatus tendinosis, tendinosis of other rotator cuff muscles, impingement, or tangent signs. The most prominent result of this study was the significantly higher prevalence of diabetes mellitus and hypertension among sarcopenic patients (p<0.001). Another important finding was that the tangent sign, a radiological indicator of rotator cuff atrophy, did not change with the presence of sarcopenia; however, it was more frequently positive in patients aged 60 years or older (p=0.013). Conclusion: While sarcopenia was not associated with differences in rotator cuff pathology or radiological atrophy as indicated by the tangent sign, it was significantly linked to a higher prevalence of diabetes mellitus and hypertension. Age, rather than sarcopenia, appeared to influence the presence of radiological markers of rotator cuff atrophy.
