*Scale 0 (DU-associated problems had no effect) to 10 (DU-associated problems completely affected the patient's ability to carry out that type of activity) transformed into percentage.
†Overall work impairment (expressed as percentage) calculated as the sum of work time missed and lost productivity at work (work time attended multiplied by work impairment percentage).
DUs, digital ulcers; n, number of patients.
