Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Rate of healing at 12 and 20 weeks (complete healing was defined as complete re-epithelialisation of the wound). | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluated at 12 weeks: 1. Mean healing time 2. Time to achieve 50% area reduction 3. Weekly percentage of ulcer area reduction Registered during the entire course of the study; a specific analysis was performed at 12 weeks and at the 18 months follow-up: 4. Number and severity of adverse events In order to enhance the quality of the observation, the tolerability of the treatment was observed during the treatment period and at the 18 months follow-up. | — |
