Role of platelet-rich plasma in the treatment of osteoarthritis: a meta-analysis.
Synthesis in The Journal of international medical research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 2 of them syntheses 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
objectiveThe clinical efficacy of platelet-rich plasma (PRP) in the treatment of osteoarthritis remains controversial. In this paper, we evaluated the clinical efficacy of PRP in the treatment of osteoarthritis using meta-analysis, providing evidence for the selection of clinical treatment options.
methodsWe performed a computer-based search of PubMed, Embase, and the Cochrane Library databases to retrieve articles using the search terms "platelet-rich plasma", "osteoarthrosis", and "knee joint". Quality evaluation and data extraction were performed. The combined effect was assessed using RevMan 5.3 software.
resultsFive randomized controlled trials, involving 320 patients, were included in this study. No significant differences were observed in the International Knee Documentation Committee score, visual analog scale (VAS) score, or the absolute value of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score between the experimental and control groups. The absolute value of the VAS score and change in the WOMAC score were significantly decreased and patient satisfaction was increased in the experimental group, as compared with the control group.
conclusionThe findings of this meta-analysis suggest that intra-articular injection of PRP is an effective treatment for osteoarthritis that can reduce post-operative pain, improve locomotor function, and increase patient satisfaction.
