Multivariable Cox proportional hazards models for the prediction of all venous thrombosis and deep vein thrombosis -with or without pulmonary embolism only.
| Covariate | All venous thrombosis (n = 84) | DVT ± PE (n = 47) | ||
|---|---|---|---|---|
| HR (95% CI) | P-value | HR (95% CI) | P-value | |

| Age ≥65 years | 0.96 (0.61–1.50) | 0.847 | 1.44 (0.79–2.64) | 0.234 |
| Previous arterial event | 0.91 (0.54–1.52) | 0.714 | 1.12 (0.57–2.22) | 0.737 |
| Previous venous event | 5.43 (3.48–8.46) | 0.000 | 2.74 (1.41–5.29) | 0.003 |
| NLR ≥ 5 | 2.14 (1.38–3.30) | 0.001 | 2.87 (1.56–5.27) | 0.001 |
