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 assess the availability, price transparency, and pricing of platelet-rich plasma (PRP), bone marrow aspirate concentration, and stem cell injections for knee osteoarthritis (OA) among orthopaedic sports medicine (OSM) practices and alternative clinics in suburban New York and to evaluate the impact of the economic status of a population on the availability and pricing of biologic injections. Methods: Between July and September 2025, OSM practices and alternative clinics offering PRP, bone marrow aspirate concentration, or stem cell injections for knee OA were identified through American Orthopaedic Society for Sports Medicine and Arthroscopy Association of North America databases and web searches. Clinics were contacted using a standardized telephone script. Analyses used Mann-Whitney U, Fisher's exact, and Levene's tests. Associations with socioeconomic vulnerability were evaluated using the Social Vulnerability Index and Spearman correlation. Results: Seventy-six (50 OSM, 26 alternative) of 91 clinics offered orthobiologics. PRP availability was similar between groups (98% vs 92%; Conclusions: Orthobiologic injections for knee OA are widely available in suburban New York. PRP is nearly universal, stem cell injections remain concentrated in alternative clinics, and pricing is unrelated to community socioeconomic vulnerability. Clinical Relevance: Orthobiologic injections for knee OA are broadly available in suburban practice settings, with variable pricing and transparency that have implications for patient counseling and shared decision-making in an out-of-pocket market with limited clinical evidence.
