Factors associated with the risk of VTE using a stepwise multivariate logistic regression analysis.
| Odds Ratio | 95% Confidence Interval | p | |
|---|---|---|---|
| Non-invasive ventilation support | 15.530 | 6.244–38.627 | <0.001 |
| CHA2DS2Vasc Score > 3 | 3.404 | 1.362–8.513 | 0.009 |
| Cough | 3.019 | 1.265–7.202 | 0.013 |
| Neutrophils, 1000/mm3 | 1.089 | 1.015–1.169 | 0.018 |
| ECG abnormalities | 2.722 | 1.039–7.133 | 0.042 |
Variables considered in the model: diabetes, CHA2DS2-VASC SCORE, obesity, ECG abnormalities on admission, cough, dyspnea, neutrophils, C-reactive protein, non-invasive ventilation support and CHA2DS2-VASC SCORE > 3, CHA2DS2-VASC SCORE > 4.
