Criteria for wound scoring.

Score	Epidermal and dermal regeneration	Granulation tissue	Angiogenesis (day-14 wounds only)
1–3	Minimal to moderate reepithelialization	Granulation around wound edges only	Capillary density <300/mm^2
4–6	Complete reepithelialization	Granulation around wound edge and in 30%–50% of wound bed	Capillary density 300–500/mm^2
7–9	Complete reepithelialization	Thick granulation around wound edge and in >50% of wound bed	Capillary density >500/mm^2
