| Middeldorp et al.29 | 198 | 33 (17) | Elevated D-dimer |
| Chen et al.22 | 88 |
40 (46) | Elevated D-dimer, hypoalbuminemia, higher SOFA score and inpatient status |
| Cui et al.23 | 81 | 20 (25) | Elevated D-dimer, older age, lower lymphocyte counts, longer APTT |

| Leonard-Lorant, et al.33
|
106 | 32 (30) | Elevated D-dimer, ICU hospitalization, Delay from onset of symptoms to CT scan (days) |
| Fraissé et al.24 | 92 | 37 (40) | Chronic renal failure, invasive mechanical ventilation, elevated D-dimer |
| Bompard et al.34 | 135 | 32 (23.7) | More frequently hospitalized in ICU and under mechanical ventilation, longer median hospitalization duration, elevated D-dimer |
TE: thrombotic event, ICU: Intensive care unit, APTT: activated partial thromboplastin time, CT: computerized tomography, SOFA: Sequential organ failure assessment, CURB-65: Confusion, urea, respiratory rate, blood pressure, and 65 years of age or older.
