Baseline information and MRI data were extracted from a computerized database. For the collection of adverse events, all patients were contacted once by phone in 2019. Patients voluntarily provided information on whether they experienced symptomatic cerebral hemorrhage or recurrent cerebral infarction after discharge. The identification of adverse events was based on disease certificates provided by patients or their relatives.
