Rehabilitation and return to activity after platelet-rich plasma injections in chronic tendinopathies: Consensus from international experts.
Review in PM & R : the journal of injury, function, and rehabilitation, 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
backgroundThe effectiveness of platelet-rich plasma (PRP) injections in chronic tendinopathies remains debated. Although the product's characteristics play a role, the impact of postinjection recommendations remains poorly investigated.
objectiveTo establish principles and guidelines for post-PRP injection rehabilitation and return to activity/sports.
designWe conducted a Delphi survey based on a "recommendations by formal consensus" methodology. Three clinicians and researchers of the GRIIP (International Research Group on Platelet Injections), experts in sports medicine and rehabilitation, performed a comprehensive literature review of MEDLINE, searching for (1) rehabilitation protocols after PRP injection for chronic tendinopathy and (2) fundamental studies of tendon healing. This review highlighted the main points to be clarified to establish a standardized post-PRP injection protocol. Fourteen points were identified, grouped into three dimensions (immediate postprocedure, rehabilitation, and follow-up and resumption of sports/activity). With a modified Delphi method, the propositions were submitted to a panel of 23 experts from five French-speaking countries. The recommendations were classified as appropriate or not appropriate, with strong or relative agreement, or uncertain when consensus was not reached.
resultsTen recommendations (postprocedure avoidance of nonsteroidal anti-inflammatory drugs, rehabilitation principles and timeline, follow-up) were classified as appropriate: six with strong and four with relative agreement; four propositions regarding immediate postprocedure were deemed uncertain.
conclusionAgreement was reached for 10 of the 14 recommendations but with low level of evidence, mainly based on experts' opinion. This work should help standardize a post-PRP injection protocol for chronic tendinopathies, which will minimize bias due to variations in rehabilitation protocols in further studies.
