Fig. 10From: Hyperpigmentation after surgery for a deep dermal burn of the dorsum of the hand: partial-thickness debridement followed by medium split-thickness skin grafting vs full-thickness debridement followed by thick split-thickness skin graftingDifferences in weighted mean value of each of the color components of hue, saturation, and brightness (HSB). The absolute values of Δbrightness were significantly larger in the partial-thickness debridement (PTD) group than those in the full-thickness debridement (FTD) group. Difference (graft-control) in brightness of the PTD group is negative, indicating the graft is darker than the control. N.S. not significantBack to article page
