Clinical wound healing by investigator global assessment (IGA) of chronic wounds treated with gene-corrected autologous keratinocyte grafts^[a]. [a] A red box indicates < 50% wound healing compared to baseline, a yellow box indicates 50–74% wound healing compared to baseline, and a green box indicates ≥ 75% wound healing compared to baseline. A grey box indicates that the follow-up visit was conducted virtually due to the ongoing SARS-CoV 2 pandemic, which precluded Investigator Global Assessment (IGA) of wound healing. A striped box indicates a missed appointment. A white box indicates prospective dates. Wounds A-F were chronic wounds. Wound Z was an induced wound. Control wounds are not included. [b] Subjects 4 and 5 died prior to their year six and year five visits, respectively
