Effect of platelet‐rich plasma vs standard management for the treatment of diabetic foot ulcer wounds: A meta‐analysis

We performed a meta‐analysis to evaluate the effect of platelet‐rich plasma vs standard management for the treatment of diabetic foot ulcer wounds. A systematic literature search up to March 2022 was performed and 1435 subjects with diabetic foot ulcer wounds at the baseline of the studies; 723 of them were treated with platelet‐rich plasma, and 712 used control. Odds ratio (OR) with 95% confidence intervals (CIs) was calculated to assess the effect of platelet‐rich plasma vs standard management for the treatment of diabetic foot ulcer wounds using the dichotomous method with a random or fixed‐effect model. The use of autologous platelet‐rich plasma resulted in significantly higher complete‐healed diabetic foot ulcer wounds compared with control (OR, 1.95; 95% CI, 1.49‐2.56, P
