By Du Y, Zhang B, Meng X and 4 others.
Abstract
Purpose
The treatment of diabetic foot ulcers (DFUs) remains challenging, and the benefits and safety of platelet-rich plasma (PRP) therapy are still debated. This study analyzed existing meta-analyses on PRP therapy for DFUs to identify the most reliable evidence source.
Methods
This cross-sectional appraisal was conducted according to PRISMA 2020 guidance. PubMed, Embase, and the Cochrane Library were searched from inception to May 20, 2026, for meta-analyses comparing PRP therapy with standard or conventional care for DFUs. Only meta-analyses based exclusively on randomized controlled trials (RCTs) were included. Methodological quality was assessed using AMSTAR, evidence level was classified according to the Oxford Levels of Evidence, and discordant findings were examined using the Jadad decision algorithm.
