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
objectivesUltrasound-guided puncture and lavage (UGPL) is an established first-line therapy for chronic rotator cuff calcific tendinopathy (RCCT). However, insufficient treatment response remains common, and residual calcification may contribute to persistent tendinitis. This study examines tendon neovascularization assessed by power Doppler ultrasound (PDUS) following UGPL and evaluates its correlation with clinical symptoms.
methodsTwenty-four patients with a single, large and dense calcific deposit underwent UGPL without steroid injection and were followed for 12 months. Vascularization was quantified by PDUS using the Chiou Score and a novel Vascular Score. Patient-reported outcomes included pain intensity (Pain NRS) and the subjective shoulder value (SSV). Associations between PDUS scores and outcomes were assessed using linear mixed-effects models.
resultsRelevant PDUS signals (Chiou Score ≥2) were observed in 54% of patients at least once during the 12-month follow-up, without clustering at specific time points. Despite radiographic resolution in 70% of cases, residual calcifications remained detectable on ultrasound in all patients except 1. In the mixed-effects models including all follow-up events, PDUS scores were significantly associated with clinical symptoms. Higher Chiou and Vascular Scores corresponded to lower SSV values (Chiou Score: β = -5.91, p < .001; Vascular Score: β = -3.12, p < .001) and higher Pain NRS values (Chiou Score: β = 0.67, p = .001; Vascular Score: β = 0.34, p < .001).
conclusionPersistent tendon hypervascularization correlates with worse outcomes after UGPL, despite radiographic resolution. These findings support the concept of postinterventional "microcalcific associated tendinopathy" and highlight the potential of PDUS as a monitoring tool in the management of RCCT.
