Risks of stroke for different follow-up time interval
We also observed stroke risk in women with pre-eclampsia/eclampsia at intervals of 0-1, 1-3, 3-5, 5-10, and 10-15 years (see Table 3). Overall, the stroke risk reach peak within 1-3 years after child delivery (aHR 3.20, 95% CI=1.82-5.63, p <0.001). The risk time trends for these two stroke subtypes were different (Table 3 and as illustrated in Figure 2). The ischemia stroke risk reach peak within 1-3 after child delivery (aHR 3.09, 95% CI=1.71-5.58,p <0.001), while hemorrhage stroke reach peak within 3-5 years after child delivery (aHR 7.49, 95% CI=1.18-47.33,p =0.032). Besides, the hemorrhagic stroke risk was higher than the ischemic risk at each follow-up time interval.
