SE, standard error
*
Significant at the ·05 level, 2-sided test.
a
Chi square tests comparing the proportion of respondents with PE onset prior to GMC onset versus the proportion of respondents with GMC onset prior to PE onset.
b
Estimates are based on weighted data.
c
Unstable estimates due to small design effect.
