Parameters for macroscopic wound evaluation

Parameter	Score	Description
Graft take	Percentage (%) of vital graft from total graft	I.e., viability of the graft (pink color) and adherence to the wound bed (%)
Wound closure	Percentage (%) of total wound area that is covered by epithelium	Re-epithelialization of the wound area
Wound color	Scale 0 to 5	Compared to unaffected skin (pink, =0), + 5 = purple/red
Wound thickness (depth)	Scale −5 to 5	Level compared to normal epidermis level (=0), −5 = deep wound, +5 = raised wound
Distortion (compared to original wound shape)	Scale 0 to 5	0 = original size wound square, 5 = severe star-shaped wound area
Observer score (scar quality)	Scale 1 to 10	Compared to unaffected skin (1 = unaffected skin)
