Platelet-rich plasma for patellar tendinopathy: a randomized controlled trial correlating clinical outcomes and quantitative imaging.
Article in Radiology advances, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Background: Patellar tendinopathy is a common overuse injury in active individuals, often with incomplete recovery. Recently, platelet-rich plasma (PRP) treatment has shown promising results. Traditional qualitative markers are not reliable indicators of treatment response. Advanced quantitative imaging, such as ultrashort-echo time (UTE) MRI and US shear-wave elastography may be valuable adjuncts. Purpose: To investigate the clinical outcomes and quantitative imaging changes in adults with symptomatic patellar tendinopathy treated with PRP, needle tenotomy, or sham injection. Materials and Methods: Single-blinded prospective randomized controlled trial from April 2017 until July 2022 with 3 parallel interventions in athletes with symptomatic patellar tendinopathy: PRP, needle tenotomy, and sham injection. Visual analog scale for pain, patella tendinopathy-specific Victorian Institute of Sport Assessment Patella function, conventional US, shear wave speed (SWS), UTE T2* relaxation time (T2* Results: A total of 29 subjects (mean age, 26.1 ± 5.3 years; 82.8% men) were randomized. At 52 weeks, all groups demonstrated a significant improvement in pain, though most pronounced within the PRP group ( Conclusion: Clinical improvement was evident regardless of treatment but was greatest with PRP. SWS correlated with improvement in pain and may represent an adjunctive measure to assess healing in patellar tendinopathy. Correlative changes in T2* UTE quantitative markers suggest their potential for response assessment, but further research is needed to clarify their clinical applicability.
