The trial’s primary outcome was the proportion of participants with successful aneurysm occlusion at the 6-month follow-up. Members of the independent core laboratory reviewed the digital copies of the imaging data and assessed the degree of aneurysm occlusion. Successful aneurysm occlusion was defined as Raymond class I or II. The secondary outcomes included the following: immediately successful aneurysm occlusion rate, complete aneurysm occlusion at the 6-month and 12-month follow-ups (complete aneurysm occlusion was defined as no contrast filling in either the sac or the neck of the aneurysm); recurrence rate at the 6-month and 12-month follow-ups; clinical deterioration rate at 6-month and 12-month follow-ups (clinical deterioration was defined as an mRS score > 2 and an increase of at least 1 point); and safety data at the 1-month, 6-month and 12-month follow-ups (including adverse events, such as ischemic stroke, intraoperative or delayed aneurysm rupture, and neurological sequelae).In addition, the total coil length and coil packing density were also recorded. The coil packing density was defined by dividing the coil volume by the aneurysm volume [
