Logistic multivariate analysis of factors associated with toileting ability after primary RTSA
| Variable | OR (95% CI) | P value |
|---|---|---|
| Sex | ||
| Male | Reference | |
| Female | 2.38 (0.76-7.42) | .134 |
| BMI | ||
| <25 kg/m2 (normal weight) | Reference | |
| 25-29.99 kg/m2 (overweight) | 2.42 (0.48-12.09) | .281 |
| ≥30 kg/m2 (obese) | 2.83 (0.62-13.01) | .181 |
| Diagnosis leading to RTSA | ||
| Cuff tear arthropathy | Reference | |
| Primary OA with bone loss and intact cuff | 2.20 (0.55-8.83) | .265 |
| Preoperative toileting difficulty | ||
| No | Reference | |
| Yes | 4.56 (1.28-16.28) | .019∗ |
| Postoperative IR up back (per level) | 0.77 (0.64-0.93) | .007∗ |
RTSA, reverse total shoulder arthroplasty; OR, odds ratio; CI, confidence interval; BMI, body mass index; OA, osteoarthritis; IR, internal rotation.
In this model, an OR greater than 1 represents higher odds and an OR lower than 1 represents lower odds of having toileting difficulties after RTSA.
