Association between the rate of recurrent stroke and education attainment. There was no significant association between the rate of recurrent stroke within 1 year and education attainment (log rank = 1.103; P = 0.576; A). However, a negative association is shown between the rate of recurrent stroke within 5 years and education attainment (log rank = 8.462; P = 0.015; B).
