Fig. 5From: Noninvasive model for predicting future ischemic strokes in patients with silent lacunar infarction using radiomicsStratified analyses were performed to evaluate stroke-free survival in three significant clinical characteristic subgroups: (a) age, (b) dyslipidemia, and (c) the number of lesions. To achieve this, Kaplan–Meier survival curves of the low- and high-risk groups were compared. Small vertical tick marks indicate individual patients whose survival probabilities have been right censoredBack to article page
