The final search was updated on Aug 31, 2024. We assessed eligible studies that comparing the effects of hyaluronic acid and its derivatives with other dressings on wound healing in diabetic foot ulcer. The primary outcomes included the rate of ulcers completely healed, time to healing and adverse event. The standard mean differences (SMDs) or the odds ratios (ORs) were calculated for continuous or dichotomous data, respectively. Data were analyzed by using the Cochrane Collaboration\u2019s RevMan 5.0 software.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We assessed each included study with the Cochrane \u2018Risk of bias\u2019 tool. Seven RCTs involving 444 patients and 456 ulcers were included in our study. Hyaluronic acid may improve the complete ulcer healing rate (OR 3.92, 95% CI 1.74 to 8.81, P = 0.02, I<jats:sup>2<\/jats:sup> = 62%) and shorten the time to ulcer healing (SMD = -0.83, 95% CI -1.13 to
