Table 3.
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 |

|
|
> 10 to 20 |
Moderate |
2 |
|
|
> 20 |
Severe |

c) The final osteophyte score, bone opacity score, joint effusion score and global score were summed to give the overall score (maximum possible 12) | ||||
