Table 5 Univariate analysis of the association of knee osteoarthritis progression and progression of osteoarthritis at other anatomical sites.
| Progressors at other anatomical sites of OA | Knee OA | |||||
|---|---|---|---|---|---|---|
| Knee OS progressors | Knee OS non‐progressors | OR (95% CI) | Knee JSN progressors | Knee JSN non‐progressors | OR (95% CI) | |
| Hand osteophytes | 30 | 10 | 2.5 (0.6 to 10.0) | 10 | 25 | 0.6 (0.1 to 2.6) |
| Hand JSN | 25 | 7 | 1.8 (0.4 to 7.7) | 15 | 26 | 0.4 (0.1 to 1.2) |
| Hip osteophytes | 14 | 7 | 0.8 (0.2 to 3.5) | 8 | 6 | 2.5 (0.6 to 10.0) |
| Hip JSN (mm) | 33 | 16 | 0.9 (0.4 to 2.1) | 24 | 25 | 2.0 (1.0 to 4.2) |
| Lumbar spine AO | 30 | 11 | 1.4 (0.6 to 3.3) | 16 | 16 | 1.7 (0.8 to 4.0) |
| Lumbar spine DSN | 29 | 4 | 4.5 (1.3 to 15.5) | 17 | 10 | 2.9 (1.2 to 7.5) |
Except where otherwise indicated, values are numbers of patients.
AO, anterior osteophytes; BMI, body mass index; CI, confidence interval; DSN, disc space narrowing; JSN, joint space narrowing; OA, osteoarthritis; OR, odds ratio; OS, osteophytes.
