Eight women did not have a study entry sample available for analysis and their fifteen subsequent samples were excluded. Therefore, a total of 2,599 samples were available for this analysis (diabetes, n = 524; chronic hypertension, n = 827; multifetal gestation, n = 574; and previous preeclampsia, n =  674) from 993 women (diabetes, n = 194; chronic hypertension, n = 313; multifetal gestation, n = 234; and previous preeclampsia, n = 252). The original trial included 2,539 women so this analysis represents 39% of the women originally studied. Within each of the high-risk groups, women in this analysis (i.e. women with samples) were similar to women not included (i.e. without samples) for the following characteristics: primigravida, smoking, maternal age and body mass index. There were fewer African American and more Caucasian in the diabetes group and fewer other and more Caucasian in the multifetal group compared to women without a sample. The gestational age at study entry was also slightly earlier in women with samples in the multifetal gestation group compared to women without a sample. Lastly, blood pressure at study entry was slightly lower in women with chronic hypertension and slightly higher in multifetal gestation compared to women without a sample (data not shown).","tracks":[]}
