Clinical application of multi-parameter ultrasonic assessment for grading rotator cuff injuries: development and validation of a novel scoring system.
Article in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRotator cuff injuries, a leading cause of shoulder pain and dysfunction, present significant diagnostic challenges. While MRI is the diagnostic gold standard, ultrasonography (US) offers a cost-effective alternative but lacks standardization. This study addresses this gap by developing and validating a novel multiparameter ultrasonic scoring system to increase the diagnostic accuracy and clinical applicability of shoulder ultrasonography for rotator cuff pathology.
methodsA retrospective diagnostic accuracy study of 252 patients with suspected rotator cuff injury was analyzed. Independent predictors identified through multivariable logistic regression included tear width, tendon swelling, synovial effusion, and vascular score, which were integrated into a weighted composite scoring system. Diagnostic performance was evaluated using receiver operating characteristic (ROC) curve analysis.
resultsThe scoring system demonstrated excellent discriminative ability, with an area under the ROC curve (AUC) of 0.92. An optimal diagnostic threshold of > 4 points yielded a sensitivity of 82.2% and a specificity of 94.0%. This system enabled risk stratification into three tiers. Multivariate analysis confirmed tear width, degree of tendon swelling, synovial effusion, and vascular score as key diagnostic indicators.
conclusionThis ultrasonic scoring system introduces a standardized, quantitative approach to rotator cuff diagnostics, designed to reduce interobserver variability and enhance diagnostic reliability. By stratifying patients into risk categories, it facilitates personalized treatment planning. However, as this represents the initial development and internal validation phase, further prospective and external validation studies are warranted to confirm its broader applicability.
