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
backgroundAdhesive capsulitis involves capsular fibrosis and restricted shoulder movements, particularly external rotation and abduction. Magnetic resonance imaging (MRI) enables assessment of capsular and ligamentous thickening. The relationship between capsular thickness, range of motion (ROM), and rotator cuff and biceps tendon pathologies remains unclear. This study aimed to investigate the relationship between the coracohumeral ligament and inferior glenohumeral capsule thickness, shoulder range of motion, and MRI-detected edema patterns in patients with adhesive capsulitis.
methodsThis prospective study included 100 adhesive capsulitis patients who underwent shoulder MRI between July 2024 and July 2025. Coracohumeral ligament (CHL) and inferior glenohumeral capsule (IGHC) thicknesses were measured, and rotator cuff and biceps tendon pathologies graded. Shoulder ROM in external rotation (ER) and abduction was measured using a goniometer. Analyses included correlation tests, multiple linear regression, and Kruskal-Wallis tests.
resultsThe mean patient age was 57.7 ± 11.9 years, with 66% women. CHL thickness strongly negatively correlated with ER ROM (r = -0.82, P < .001), while IGHC thickness strongly negatively correlated with abduction ROM (r = -0.79, P < .001). Regression analysis showed that CHL thickness independently predicted ER limitation, and IGHC thickness predicted abduction limitation. Rotator cuff and biceps tendon pathologies were common but not independently associated with ROM.
conclusionCoracohumeral ligament and IGHC thickening are key determinants of restricted shoulder mobility in adhesive capsulitis. Magnetic resonance imaging assessment of these structures provides reliable diagnostic markers and can guide treatment, while concomitant rotator cuff and biceps pathologies have a limited impact on ROM restriction.
