Relation of the presence of baseline and progressive knee osteoarthritis defined by joint space narrowing and osteoarthritis at other anatomical sites
| OA at other anatomical sites | Baseline knee OA assessed by JSN (n = 148) | Knee JSN progressors (n = 51) | Knee JSN non-progressors (n = 97) |
|---|---|---|---|
| Values are numbers of patients. | |||
| AO, anterior osteophytes; BMI, body mass index; DSN, disc space narrowing; JSN, joint space narrowing; OA, osteoarthritis; OS, osteophytes. | |||
