Table 2.

Scoring scheme for skin injuries (26).

Score	Definition
0	No injuries
1	A small number (<5) of superficial scratches
2	A mean number (5–10) of superficial or a small number of deep scratches (<5)
3	A high number (>10) of superficial or a mean up to a high number of deep scratches (>5)

Superficial injuries were defined as those of the outer skin layers with a minimal reddening or little bleeding at this position. Instead of a blood spot, there could also be a scab. Deep injuries were those that penetrated to the lower skin layers, with reddening, bleeding or scabbing. Furthermore, necrotic or purulent injuries were possible as well.
