(A) Kaplan–Meier curves of the complete cohort, (B) stratified by bleeding as mode of presentation (hemorrhage as mode of presentation shown in red), and (C) stratified by CM localized in the spinal cord (lesion located in the spinal cord shown in red) over a 10-year follow-up. CM cavernous malformation; ISCM intramedullary spinal cord CM; MOP mode of presentation. Note: The numbers of patients at risk are shown on top of the x-axis of each graph. Log-rank test showed significant differences between groups in B and C.
