- Proportion of participants who have DFU wound recurrence by 16 weeks after complete wound healing [ Time Frame: 1 up to 16 weeks after wound closure ]
- Time to DFU wound recurrence after complete wound healing [ Time Frame: Up to 16 weeks after wound closure ]
- Participant self-report of DFU wound recurrence [ Time Frame: 16 weeks ]
- Clinician assessment of DFU wound recurrence [ Time Frame: 16 weeks ]Concordance between participant self-report and clinician assessment of DFU wound recurrence is important to provide confidence in the use of patient-reports for the primary endpoint.
