The efficacy and safety of platelet rich plasma and hyaluronic acid in the treatment of knee osteoarthritis: a meta-analysis.
Review in Frontiers in surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 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
Purpose: To investigate the efficacy and safety of intra-articular injection ratio of platelet rich plasma (PRP) and hyaluronic acid (HA), and provide evidence-based strategies for the treatment of knee osteoarthritis (KOA). Methods: Search PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Wanfang databases to retrieve literature published from the beginning of database establishment to October 2024. Include in published randomized controlled trials (RCTs) or cohort studies. The research subjects are KOA patients, with the experimental group receiving intra-articular injection of PRP and the control group receiving intra-articular injection of HA. Quality evaluation of the inclusion of Cochrane Handbook risk assessment tools using RevMan5 Perform meta-analysis on outcome measures using three software. Results: 18 articles were included, with a total of 1,326 patients. PRP showed significantly better WOMAC scores at 6 months (SMD=-8.32, Conclusion: PRP has a good clinical therapeutic effect on KOA. Based on this meta-analysis, compared with simple intra-articular injection of HA, PRP can improve WOMAC score, VAS score, and IKDC index score after 6 months of treatment, and enhance patients' health status. In terms of the incidence of adverse events, the safety of the two treatment options is similar.
