Association between hip pain and definite hip ROA within sensitivity analyses
| Analyses | Painful hips included | Prevalence K&L ≥2 in painful hips, n/N (%) | Pain-free hips included | Prevalence K&L ≥2 in pain-free hips, n/N (%) | OR (95% CI) |
|---|---|---|---|---|---|
| Primary analysis | All painful hips | 105/789 (13.3) | All pain-free hips | 113/1193 (9.5) | 1.51 (1.16 to 1.98) |
| Sensitivity analysis II | All painful hips | 105/789 (13.3) | Pain-free hips of participants without any hip pain | 70/818 (8.6) | 1.71 (1.19 to 2.46) |
| Sensitivity analysis III | Painful hips without concurrent knee pain | 40/217 (18.4) | Pain-free hips without concurrent knee pain | 11/117 (9.4) | 2.30 (1.26 to 4.19) |
| Sensitivity analysis IV | Painful hips with concurrent knee pain | 65/572 (11.4) | Pain-free hips with concurrent knee pain | 102/1076 (9.5) | 1.25 (0.91 to 1.72) |
K&L = Kellgren and Lawrence. OR = odds ratio. ROA = radiographic osteoarthritis.
