SCORE	Macroscopic findings	Cellular reaction*)	Fibrosis	ICAM1 and PECAM1 staining
0	No adhesions	None	None	None
1	Thin and narrow, easily separable adhesions	Rare	Rare	<10%
2	Thick adhesions, limited to one area	Mild	Mild	10-50 %
3	Thick and wide adhesions	Severe	Severe	>50%
4	Thick and wide adhesions between the organs and the abdominal wall	NA**)	NA**)	NA**)

^*: Giant cell, lymphocyte/plasmocyte, neutrophil, and histiocyte reactions. ^**NA: not available.
