pregnancies with a relative risk of 6.4 (95% CI,3.0 to 13.5). Among women who had been pregnant
three or more times, preeclampsia during one pregnancy was associated with a relative risk of
ESRD of 6.3 (95% CI, 4.1 to 9.9), and preeclampsia during two or three pregnancies was associated with a relative risk of 15.5 (95% CI, 7.8 to 30.8).Figure 1 shows the association between preeclampsia and ESRD during the follow-up period.Separate analyses setting the baseline at 10 years after the pregnancy of interest confirmed a significant association between preeclampsia and ESRD. These analyses showed that after one pregnancy, the relative risk of ESRD that was associated with preeclampsia was 4.1 (95% CI, 3.1 to
