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
