| Observations | Prevalence (%)† | κ Value | ||||
|---|---|---|---|---|---|---|
| Consultant | Spec reg | Nurse | Cons/spec reg | Cons/nurse | Spec reg/nurse | |
| *p<0.05, **p<0.01; †prevalence is the percentage of affected shoulders which were found to test positive; ‡McNemar p<0.05 denoting significant difference in prevalence between the two raters. | ||||||
