Figure 1 Trial profile Initial screen failures were mostly attributable to non-qualifying wound size, failure to confirm the diagnosis with duplex doppler ultrasonography, and low serum pre-albumin concentration. ITT=intention-to-treat. *Voluntary discontinuation. †Excluding one patient who died of unrelated causes before starting study treatment.

Figure 3 Cox proportional hazards analysis of wound healing The Cox proportional hazards model incorporates a comparison of healed versus open wounds across treatment groups at each of the weekly trial visits, with censoring of missing data. The HR is the likelihood of healing at any given point in time, by group, relative to the vehicle control group. CIs show the range of potential values. HR=hazard ratio.
