Relation of the presence of baseline and progressive knee osteoarthritis defined by osteophytes and osteoarthritis at other anatomical sites
| OA at other anatomical sites | Baseline knee OA assessed by OS (n = 133) | Knee OS progressors (n = 89) | Knee OS non-progressors (n = 44) |
|---|---|---|---|
| Values are numbers of patients. | |||
| AO, anterior osteophytes; BMI, body mass index; DSN, disc space narrowing; JSN, joint space narrowing; OA, osteoarthritis; OS, osteophytes. | |||
