Multivariate analysis of patient-related factors that influence achievement of MCID and SCB
| Outcome measure and significant variable | Odds ratio | 95% CI | p value |
|---|---|---|---|
| MCID based on ≥ 13.5 point increase in ASES score | |||
| Preoperative ASES score | 0.96 | 0.94–0.98 | <0.001 |
| Procedure: RSA vs TSA | 0.36 | 0.16–0.85 | 0.016 |
| SCB based on ≥ 36.6 point increase in ASES score | |||
| Preoperative ASES score | 0.91 | 0.89–0.92 | <0.001 |
| Living arrangement: (reference: with partner/spouse) | |||
| Alone | 0.36 | 0.19–0.69 | 0.002 |
| Diagnosis: cuff tear arthropathy vs osteoarthritis | 0.14 | 0.07–0.30 | <0.001 |
| Comorbidity: back pain | 0.42 | 0.24–0.71 | 0.002 |
ASES = American Shoulder and Elbow Surgeons; RSA = reverse shoulder arthroplasty; TSA = total shoulder arthroplasty; MCID = minimal clinically important difference; SCB = substantial clinical benefit.
