| Cam/pincer morphology | Symptoms (+) vs Symptoms (−) | 0.64 | 0.31–1.33 |
| Cam/pincer morphology | FADIR (+) vs FADIR (−) | 0.86 | 0.39–1.88 |
| Right side | |||
| FADIR test | Symptoms (+) vs Symptoms (−) | 5.26 | 2.60–10.64 |

| Cam/pincer morphology | FADIR (+) vs FADIR (−) | 1.18 | 0.51–2.78 |
Cam morphology was defined as alpha angle > 60° and pincer morphology was defined as LCE angle > 40°. OR were obtained from logistic regression adjusted for age, sex, and BMI. FADIR: flexion-adduction-internal-rotation test; LCE: lateral center edge; BMI: body mass index.
