Cox regression modelling of clotting defects and survival in IPF
| Clotting defect | Number of deaths | Person-years | Mortality rate per 1000 person years (95% CI) | Hazard Ratio (95% CI)* | Hazard Ratio (95% CI)# | p value |
|---|---|---|---|---|---|---|
| No clotting defects | 8 | 86.7 | 92.3 (46.2–184.6) | 1.00 | 1.00 | 0.0013 |
| Prothrombotic state | 78 | 298.9 | 257.6 (206.1–322.1) | 2.85 (1.37–5.93) | 2.77 (1.28–5.99) | 0.0039 |
