Ultrasonographic Findings in Periarthritis of the Shoulder and Their Correlation With Clinical Severity.
Article in Cureus, 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
introductionPeriarthritis (PA) of the shoulder is a common cause of pain and disability. Although MRI is the standard imaging modality, ultrasonography (USG) is a cost-effective and accessible alternative. However, evidence correlating USG findings with clinical severity in Indian settings remains limited. This study evaluated the ultrasonographic findings in PA of the shoulders and determined their correlation with clinical parameters, including pain, disability, and passive range of motion (PROM).
methodsThis cross-sectional study included 79 patients with unilateral PA of the shoulder at a tertiary care academic institute in India. Pain was assessed using the Visual Analogue Scale (VAS), disability using the Shoulder Pain and Disability Index (SPADI), and PROM using a universal goniometer. Bilateral shoulder USG was performed to measure coracohumeral ligament (CHL) thickness, rotator interval (RI) thickness, axillary recess (AR) thickness, and long head of biceps tendon (LHBT) effusion. Statistical analysis included t-tests and correlation coefficients.
resultsUSG parameters were significantly higher on the affected side compared to the unaffected side: CHL (2.73 ± 0.66 vs 2.09 ± 0.63 mm), RI (1.72 ± 0.53 vs 1.39 ± 0.35 mm), AR (3.85 ± 1.57 vs 2.30 ± 1.09 mm), and LHBT effusion ((1.40 (0.00-3.00) vs 0.00 (0.00-1.00) mm) (p < 0.001). PROM was significantly restricted in all movements. No significant correlation was observed between USG parameters and VAS or SPADI scores. However, AR thickness showed a fair positive correlation with PROM restriction (p < 0.05).
conclusionUSG reliably detects structural changes in patients with shoulder pain and limited PROM in one clinically relevant plane. AR thickness correlates with functional limitation and may serve as a useful imaging marker.
