Objective To determine whether the topical application of platelet-rich plasma (PRP) promotes healing in experimentally-induced full-thickness skin wounds in animals, a systematic review and meta-analysis will be performed.MethodsWeb of Science, Cochrane Library, PubMed, Research Gate, Cochrane Wounds Group, and Veterinary Information Network will be searched to identify randomised and not randomised controlled clinical trials comparing PRP with placebo or with other treatments in animals. Primary outcome: reduction of open wound area; secondary outcomes: healing time and number of healed cases. Effect sizes: Hedges’ g; odds ratio.
