"This study was a retrospective investigation of the prospectively collected data from the Jrecan trial between 1 March 2018 and 30 June 2019, which was named as the training set. The Jrecan trial was a prospective, multicenter, randomized, non-inferiority clinical trial comparing the efficacy and safety of two MT stents (the Jrecan revascularization device and the Solitaire device) in patients with AC-LVO stroke. The trial involved 16 comprehensive stroke centers in China. Each center handled more than 50 cases of MT annually, and each neuro-interventionalist performed at least 10 MT procedures per year. The Jrecan trial was approved by the ethics committees of the participating centers and was duly registered with the Chinese Clinical Trial Registry, http://www.chictr.org.cn/showproj.aspx?proj=23396, identifier ChiCTR-TOC-17013822. The patient data for the validation set were retrospectively collected from Baotou Center Hospital between January 2013 and December 2020 and approved by the ethics committee of Baotou Center Hospital. Informed consent was obtained from the participants or their legal representatives. The flowchart of the patient profile is shown in ."
