Multivariate Analysis of TTP in PETs.
| Hazard Ratio (95% Confidence Interval) | P | |
| Low ARHI expression | 4.0 (1.5 – 11.1) | .007 |
| Ki67 ≥5% | 8.3 (2.8 – 24.8) | .0002 |
Hazard ratio represents an estimate of the ratio of mortality rate in patients with low ARHI expression versus patients with normal ARHI expression, or patients with proliferation index Ki67 <5% versus patients with Ki67 ≥5%. Cox proportional hazard model was used with simultaneous inclusion of all factors shown.
