Cox proportional hazards regression model for other MOM versus ASR™ implants
| Implant | Crude hazards regression (95% CI) | p value | Adjusted hazards regression (95% CI)* | p value |
|---|---|---|---|---|
| Other MOM | 1.0 (reference) | 1.0 (reference) | ||
| ASR | 6.1 (3.5–11) | < 0.001 | 6.1 (3.4–11) | < 0.001 |
