QUESTION: Can a simple prediction rule be derived to identify patients in whom venous leg ulcers will heal within 24 weeks using limb compression bandages?


2 cohort studies—1 for derivation and 1 for validation of the prediction model.


Derivation was done in a retrospective cohort from a cutaneous ulcer centre in a university hospital in Philadelphia, Pennsylvania, USA. Validation was done in >20 US clinical sites.
