The effect of robenacoxib on the concentration of C-reactive protein in synovial fluid from dogs with osteoarthritis

Table 3 Details of the radiographic scoring scheme

a) For each of 11 different sites, the size of osteophytes was measured in millimetres and a score was assigned:
0	Absence of osteophytes
1	Osteophytes smaller than 2 mm
2	Osteophytes between 2 and 5 mm
3	Osteophytes greater than 5 mm
b)The osteophyte score for each site was totaled and then converted to a final score of 1-3
From 0 to 10	Mild	1
> 10 to 20	Moderate	2
> 20	Severe	3
c) The final osteophyte score, bone opacity score, joint effusion score and global score were summed to give the overall score (maximum possible 12)
Parameter	Absent	Mild	Moderate	Severe
Osteophytes	0	1	2	3
↑ Bone opacity	0	1	2	3
Joint effusion	0	1	2	3
Global score	0	1	2	3
				Total maximum score 12
