| Expected correlations |
---|---|
1. OSIS and WOSI | ≥0.7 |
2. OSIS and SST | ≥0.6 |
3. OSIS and OSS | ≥0.6 |
4. OSIS and DASH | ≥0.6 |
5. Correlation between OSIS and body-part-specific PROMs (SST, OSS, and DASH) should be at least 0.1 higher than that between OSIS and the generic SF-36 subscales | |
6. Correlation between OSIS and SF-36 physical function scale should be at least 0.1 higher than the correlations between OSIS and the other SF-36 subscales |
