Laboratory tests’ results and correlation with presence or absence of pulmonary embolism.
| Median (IQR) | PE (n = 65) | Non-PE (n = 49) | p-value (p < 0.001) | |
|---|---|---|---|---|
| Variables | ||||
| DD (ug/mL) | 4.47 (1.83–13) | 8.39 (3.19–23.2) | 2.61 (1.17–4.97) | <0.001* |
| CRP (mg/dL) | 11.5 (2.65–25.5) | 6.2 (3.7–27.4) | 13.2 (2–22.2) | 0.096 |
| INR | 1.08 (1.02–1.16) | 1.06 (1.05–1.19) | 1.10 (1–1.13) | 0.056 |
| aPTT | 1.03 (0.92–1.17) | 1.03 (0.91–1.2) | 1.03 (0.94–1.15) | 0.978 |
| Platelets count (109/L) | 261 (176–361) | 258 (172–361) | 265 (178–348) | 0.702 |
| Fibrinogen (mg/dL)^ | 534 (396–750) | 612 (402–609) | 506 (384–838) | 0.163 |
Data presented as median (IQR). Differences with two-sided p-values below 0.001 deemed as statistically strongly significant and marked with *. PE: pulmonary embolism; DD: d-dimer; CRP: C-reactive protein; INR: international normalized ratio; aPTT: activated partial thromboplastin time; ^: plasma levels.
