ICC (for all 6 readers and bootstrap CI based on 1000 bootstrap weights) for summed BML and synovitis-effusion scores in cross-sectional and 2 timepoint (baseline, 8 weeks) MRI scans.
| Exercise 1, n = 20 | Exercise 2*, n = 45 Status Score | Exercise 2, n = 18 Change Score | |
|---|---|---|---|
| HIMRISS femoral BML | 0.52 (0.27–0.76) | 0.83 (0.74–0.90) | 0.81 (0.49–0.90) |
| HIMRISS acetabular BML | 0.61 (0.29–0.83) | 0.81 (0.73–0.87) | 0.49 (0.34–0.63) |
| HIMRISS synovitis-effusion | 0.70 (0.49–0.83) | 0.66 (0.54–0.76) | 0.35 (0.04–0.60) |
| HIMRISS total | 0.58 (0.36–0.77) | 0.84 (0.77–0.88) | 0.77 (0.47–0.90) |
| HOAMS BML total | 0.52 (0.36–0.66) | 0.85 (0.78–0.90) | 0.71 (0.44–0.83) |
| HOAMS synovitis | 0.46 (0.22–0.66) | 0.62 (0.47–0.74) | 0.58 (0.05–0.80) |
↵* HOAMS synovitis assessment was conducted on coronal STIR scans in exercise 2 by 5 readers. BML: bone marrow lesion; HIMRISS: Hip Inflammation MRI Scoring System; HOAMS: Hip Osteoarthritis MRI Scoring System; MRI: magnetic resonance imaging; ICC: intraclass correlation coefficient.
