The institutes used a wide variety of dressings including absorbent pad, alginate, antimicrobial, foam, gauze, and other types. About a third were antimicrobial.
In the intent-to-treat population at 12 weeks, the median percentage area reduction of the ulcers was 89% in the treatment group, compared with 47% in the control group (P = .016).
The researchers reported significantly fewer serious adverse events in the treatment group, and none were reported to be linked to the various dressings used.
According to Dr. Edmonds, pricing information for the treatment is unavailable.
