Trial profile. A total of 553 consecutive patients with ICH were admitted. Of these patients, 492 were admitted to the General Hospital of Beijing Military Region and 61 were admitted to the Xianghe Hospital. Based on the inclusion/exclusion criteria, 355 were excluded, and 198 were available according to the per protocol sample. Of those, 84 received minimally invasive puncture and drainage (group A), and 114 underwent decompressive craniectomy (group B) hematoma evacuations. Nine were lost during follow up at 30 days (1 and 4) and 1 year (1 and 3 in group A and group B, respectively). For those patients, their last observed data were used as their final results for intention-to-treat analysis.
