Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Unfractionated Heparin (UFH) Alone | Patients in this arm received the standard of care: intravenous unfractionated heparin used as anticoagulation treatment. | 4 | 29 | EG000 |
| Group 2 | UFH + EkoSonic | Patients in this arm received anticoagulation (intravenous unfractionated heparin) plus the EkoSonic Endovascular System was used to deliver a low dose of \<20mg rt-PA (Actilyse) directly into the occlusive pulmonary thrombus. | 3 | 30 | EG001 |
