Table 4.
Possible radiographic hip osteoarthritis (RHOA) and clinical symptoms of hip osteoarthritis in Osteoarthritis Initiative. RHOA (possible) as diagnostic test. Clinical symptoms of hip osteoarthritis as gold standard (symptoms versus none). Values are percentages (number with pain/total number)
| Pain definition* | Sensitivity | Specificity | Positive predictive value | Negative predictive value | |
|---|---|---|---|---|---|
| % of gold standard hips with RHOA | % of non-gold standard hips without RHOA | % of RHOA hips with gold standard | % of non-RHOA hips without gold standard | ||
| Groin pain† | 28.3 (67/237) | 81.7 (6934/8495) | 4.1 (67/1628) | 97.6 (6934/7104) | |
| Anterior thigh pain† | 29.9 (47/157) | 81.6 (6994/8575) | 2.9 (47/1628) | 98.5 (6994/7104) | |
| Groin or anterior thigh pain† | 30 (97/323) | 81.8 (6878/8409) | 6.0 (97/1628) | 96.8 (6878/7104) |
*All definitions require pain on most days of a month in past year.
†Hips with pain but not in specific location are classified as no pain. Location specific pain includes hips with pain also in other locations.
