What the authors reported
This Cochrane review pooled 3 small randomized trials (212 participants): one found greater ulcer-area reduction and shorter hospitalization with ozone versus antibiotics, but pooled analysis of the other two found no significant difference from usual care in ulcer healing, adverse events, or amputation rate.
What limits this result
Only three included trials, all judged at high or unclear risk of bias; the review authors conclude they are unable to draw any firm conclusions about effectiveness.
Other ozone methods, such as major autohemotherapy, that clinics cite in support of EBO2. A result for one method does not transfer automatically to another. One study rarely settles a medical question; our guides weigh each paper against the rest of the evidence.
