Application of shear wave elastography and B-mode ultrasound in patellar tendinopathy after extracorporeal shockwave therapy.
Article in Journal of medical ultrasonics (2001), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
purposeThe purpose of this study was to investigate changes in morphological and elastic properties, as estimated by B-mode ultrasound (B-US) and shear wave elastography (SWE), in volleyball athletes with patellar tendinopathy (PT) and changes after extracorporeal shockwave therapy (ESWT) as well as their relationships with US measurements and Victorian Institute of Sport Assessment-Patella (VISA-P) scores in PT.
methodsTwelve healthy athletes (24 patellar tendons) and 31 volleyball athletes with PT (48 tendons) were included. All were examined by US and received VISA-P scores before the start of the study. The athletes received 3 months of ESWT and underwent US and VISA-P at 1 month and 3 months. VISA-P scores were used to evaluate therapeutic efficacy. Tendon thickness and cross-sectional area (CSA) were detected by B-US, and the elastic modulus was measured by SWE. Correlations between VISA-P and US measurements were calculated.
resultsThickness, CSA, and elastic modulus of the patellar tendon in PT were higher than those in healthy athletes (P < 0.000). In PT with ESWT, VISA-P scores decreased by 22.1% (P < 0.000) and thickness decreased by 11.2% relative to baseline (P < 0.000). CSA decreased by 1.4% (P < 0.000). The elastic modulus decreased by 15.2% (P < 0.000). Elastic modulus, thickness, and CSA had significant negative correlations with VISA-P scores (P ≤ 0.005), with a stronger correlation between elastic modulus and VISA-P.
conclusionAthletes with PT had stiffer and larger tendons than healthy athletes. SWE combined with B-US could clearly show the changes in tendon thickness, CSA, stiffness in PT, and changes after treatment. SWE combined with B-US provided visualization with quantitative, reproducible, and noninvasive imaging in the follow-up evaluation of PT and is worth promoting clinically.
