Table 3.

Explanation of used scale of the semi-quantitative analysis of histological sections (ST—surrounding tissue, i.e., tissue out of GT; DL—demarcation line; SCT—subcutaneous tissue; GT—granulation tissue).

Scale	Epithelialization	PMNL	Fibroblasts	Luminized Vessels	Collagen
0	thickness of cut edges	absent	absent	absent	absent
1	migration of cells (<50%)	mild ST	mild-ST	mild-SCT	minimal-GT
2	migration of cells (≥50%)	mild DL/GT	mild-GT	mild-GT	mild-GT
3	bridging the excision	moderate DL/GT	moderate-GT	moderate-GT	moderate-GT
4	keratinization	marked DL/GT	marked-GT	marked-GT	marked-GT
