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
