Randomized Clinical Trial of the Innovative Bilayered Wound Dressing Made of Silk and Gelatin: Safety and Efficacy Tests Using a Split-Thickness Skin Graft Model

Table 3

The median healing time of split-thickness skin graft donor sites in each dressing.

The healing time of split-thickness skin graft donor sites (days)
	Median ± IQR (range)
Bactigras	14.0 ± 6.0 (9–19)
Bilayered wound dressing	11.0 ± 6.0 (7–18)

Significant difference ( versus Bactigras), calculated by a Wilcoxon signed rank test.
