FIGURE 2.

The cumulative incidence (%) of intracranial hemorrhage (ICH) in patients with preeclampsia and matched controls. Kaplan–Meier analysis of the cumulative incidence of ICH over time among patients with preeclampsia and the matched group. The survival curves were compared using the log-rank test. Although the results are similar to those shown in Figure 1, the difference in Figure 2 is more significant by the log-rank test (P < 0.0001) than the results of Figure 1. However, the Kaplan–Meier curve revealed that subsequent ICH occurs much earlier and the overall ICH risk is much higher in the patients with preeclampsia (eg, a more severe form of pregnancy-induced hypertension than gestational hypertension) than the matched group.
