Table 4.
Severity, treatment discontinuation, time to the first episode, and median duration of pulmonary embolism in symptomatic and asymptomatic cases.
| Characteristics, n (%) | Symptomatic (n = 8) |
Asymptomatic (n = 10) |
P value a |
|---|---|---|---|
| Grade | |||
| Grade 3 | 5 (62.5) | 10 (100) | .03 |
| Grade 4 | 2 (25.5) | – | |
| Grade 5 | 1 (12.5) | – | |
| Treatment discontinuation | 2 (33.3) | 1 (10.0) | .396 |
| Median time to the diagnosis of an episode, months (IQR) | 4.8 (2.3–12.4) | 4.1 (2.8–12.2) | .756 |
| Median duration, days (IQR)b | 7.5 (6.8–16.3) | 83 (11.3–180.8) | .079 |
Data are n (%), unless otherwise specified.
aThe analyses were performed through Wilcoxon exact test for quantitative characteristics and Chi-square or Fisher’s exact tests for qualitative characteristics.
bMedian duration of pulmonary embolism in symptomatic and asymptomatic cases was evaluated until clinical symptomatology resolution or radiological disappearance, respectively. Thus, the duration of symptomatic and asymptomatic thromboembolic events is not comparable.
Abbreviation: IQR, interquartile range.
