Text: Compared with the control group with VIS alone, the group with wIRA + VIS showed better wound healing [after 9 weeks 85 vs. 675 on a 0-100 visual analogue scale (VAS), median difference 15, 95 % confidence interval (CI) 3-30, P = 0012], a higher percentage of patients with a healing trend [after 9 weeks 21 of 25 (84 %) vs. 13 of 26 (50 %), P = 0023], better granulation (after 9 weeks 90 vs. 80 on a 0-100 VAS, median difference 10, 95 % CI 0-30, P = 0036), a trend to less exudation (after 5 weeks 30 vs. 55 on a 0-100 VAS, P = 0075) and to faster reduction of the wound area (after 7 weeks 39 % vs. 195 % reduction of wound area, median difference 205 %, 95 % CI -4 -49 %, P = 010 ; for wounds with an initial area < 10 cm (2) : after 13 weeks 92 % vs. 47 % reduction of wound area, median difference 30 %, 95 % CI 0-68 %, P = 011).
