To evaluate the efficacy and safety of topical oxygen therapy (TOT) in diabetic foot ulcers (DFUs), researchers systematically retrieved relevant studies from PubMed, EMBASE, Web of Science, CENTRAL and ClinicalTrials.gov. Relevant studies were searched from database inception to January 2022. Two researchers independently screened the literature, extracted data and assessed the quality of the included studies. Statistical analysis was performed in Stata 16.0. A total of seven RCTs involving 614 participants were included. Compared with the control group, the TOT group had a higher healing rate (RR = 1.63, 95% CI [1.33, 2.00]). According to descriptive analysis, TOT reduced the ulcer area and improved healing durability and quality of life. Furthermore, it had no effect on the occurrence of adverse events. However, it was unclear whether it would be able to reduce the healing time. The existing evidence suggests that TOT is effective and safe for chronic DFUs. Further studies are warranted to validate our findings.
