This study is a prospective randomized controlled pilot study evaluating the efficacy and safety of an OEOd-based wound dressing compared with standard wound care in patients with post-surgical diabetic foot ulcers. Participants were randomly assigned at enrollment to receive either the OEOd-based dressing or standard therapy. The primary outcome was complete ulcer healing at 16 weeks. Secondary outcomes included new infections, need for additional surgical debridement, re-hospitalization, and time to healing. The study was designed to provide preliminary estimates of treatment effect and feasibility to inform future larger randomized trials.
