Patient-reported pain and itch at treated chronic RDEB wounds, stratified by wound healing. Summary of treated chronic RDEB wounds with (A) pain (binary option: yes/no) and (B) itch (binary option: yes/no), stratified by wounds demonstrating < 50% wound healing and ≥ 50% wound healing as determined by investigator global assessment (IGA). Statistically significant differences in pain and itch by graft site healing were estimated by Fisher’s exact test
