Maternal pre-pregnancy BMI, early pregnancy TG concentration, early pregnancy blood pressure and absolute risks for preeclampsia
We further analyzed the association between maternal pre-pregnancy BMI, early pregnancy blood pressure and the risks for preeclampsia (Figure 2 ). Frequencies represented the absolute risks of preeclampsia (Figure 2A, C ) and the percentage of participants (Figure 2B, D ) for the combination of either pre-pregnancy BMI and maternal early pregnancy blood pressure (Figure 2A, B ) or maternal TG concentrations in early pregnancy and maternal early pregnancy blood pressure (Figure 2C, D ). The absolute risks of preeclampsia increased across the whole range of maternal pre-pregnancy BMI, early pregnancy TG concentrations, and early pregnancy blood pressure (Figure 2 ). For the combination of pre-pregnancy BMI and maternal blood pressure in early pregnancy, the lowest absolute risk was 1.13% for women with normal blood pressure and a BMI below the 10th quartile, while the highest absolute risk was 14.29% for women with stage 2 hypertension and a BMI above the 90th quartile (Figure 2A, B ). For the combination of maternal TG concentrations in early pregnancy and maternal early pregnancy blood pressure, the lowest absolute risk was 1.02% for women with normal blood pressure and TG concentrations below the 10th quartile, while the highest absolute risk was 13.59% for women with stage 2 hypertension and TG concentrations above the 90th quartile (Figure 2C, D ).
