Platelet-rich plasma combined with multimodal therapy for diabetic foot ulcer with tophi: a case report.
Article in Frontiers in clinical diabetes and healthcare, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Objective: To evaluate the comprehensive therapeutic value of platelet-rich plasma (PRP) combined with antibiotic-loaded bone cement, systemic metabolic management, and topical herbal preparation for diabetic foot ulcer (DFU) with tophi. Methods: A 55-year-old male with tophaceous DFU received multimodal treatment, including debridement, antibiotic-impregnated bone cement implantation, local autologous PRP injections, topical Xiang Lei Tang Zu Ointment, and systemic control of glucose and uric acid. Efficacy was assessed via wound area, laboratory tests, and imaging. Results: After 4 months, the ulcers were nearly healed with significant reduction in wound area, healthy granulation tissue, and complete re-epithelialization. Serum uric acid decreased from 564 μmol/L to normal range, alongside reduced inflammatory markers. Conclusion: This multimodal strategy integrating local anti-infection, bioactive repair, topical agents, and systemic regulation effectively controlled infection, promoted tissue regeneration, and improved the metabolic microenvironment, offering a promising integrative model for refractory tophaceous DFU.
