Extended Data Table 1 Participant, pregnancy and preeclampsia characteristics across both discovery and validation cohorts

From: Early prediction of preeclampsia in pregnancy with cell-free RNA

  1. Maternal age and BMI, gestational age (GA) at delivery, fetal weight and GA at preeclampsia onset are reported as mean ± s.d. All other values are reported as percentages with the corresponding count in parentheses. Small for GA (SGA) was defined as an infant with a birthweight below the 10th centile for their GA at delivery. Pre-pregnancy BMI was not available for individuals in the validation 2 cohort. See Supplementary Table 2 for exact P values. AI/AN, American Indians and Alaska Natives.
  2. *P ≤ 0.05, two-sided chi-squared (categorical) or ANOVA (continuous) test comparing all cohorts with Bonferroni correction.
  3. †P ≤ 0.05, two-sided chi-squared (categorical) or ANOVA (continuous) test comparing preeclampsia and normotensive within each cohort with Bonferroni correction.
  4. ‡ denotes that missing values were omitted from reported values for a given feature.
