Short-Term Clinical Outcomes and Systemic Inflammatory Biomarker Responses Following Platelet-Rich Plasma Injection in Knee Osteoarthritis.
Article in Life (Basel, Switzerland), 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
backgroundKnee osteoarthritis (KOA) is a degenerative joint disorder characterized by chronic pain, functional limitation, and low-grade inflammation. While platelet-rich plasma (PRP) has gained traction as a biologic therapy, the relationship between short-term clinical outcomes and systemic inflammatory biomarker dynamics remains poorly understood in routine clinical settings.
methodsThis prospective observational study evaluated 40 patients with grade 2-3 KOA receiving a single ultrasound-guided intra-articular PRP injection. Clinical outcomes via the Visual Analog Scale (VAS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Short Form-36 (SF-36), alongside serum inflammatory markers (IL-1β, IL-8, IL-18, TNF-α, erythrocyte sedimentation rate, and C-reactive protein), were assessed at baseline and 4 weeks post-injection using paired tests and multivariable regression.
resultsAt 4 weeks, clinical scores improved significantly (all
conclusionsA single intra-articular PRP injection was associated with short-term clinical improvements and selected reductions in circulating IL-8 and TNF-α, although the clinical significance of these biomarker changes remains uncertain. Given the observational design and short follow-up, these preliminary findings require confirmation in larger controlled trials.
