Data are presented as n (%) or median (IQR). The data in this table are based on the data set before imputation. For some variables, the denominators are smaller than the number of patients included due to missing data.
CAS, carotid artery stenting; EVT, endovascular treatment; N/A, not applicable; PTA, percutaneous transluminal angioplasty.
