Fig. 2.

Immunohistochemical staining of vascular epithelial growth factor (VEGF) in skin. Samples of septic patients on day 4 post wounding (A) and healthy controls on day 3 (B) are shown. Septic patients have more intense staining of migrating epithelium than healthy controls. The intensity of staining is reported as absent (‐), mild (+), moderate (++) or strong (+++), and the percentages are shown (C). The arrow indicates the wound. The bar at the bottom of the figure is equal to 100 µm. Statistical significances between study groups are indicated by brackets and significant p‐values (p < 0.05) are marked with an asterisk.
