Figure 2. Differences in the mean values of SBP/DBP during pregnancy between women with HT and women without HT. Abbreviations: systolic blood pressure (SBP), diastolic blood pressure (DBP), hypertension (HT), and trimester (tri). The error bars indicate the standard deviation. *: significant differences (p < 0.05; Student’s t-test).
Figure 3. Changes in blood pressure for each gestational period relative to the nonpregnant measurements. Abbreviations: blood pressure (BP), systolic blood pressure (SBP), and diastolic blood pressure (DBP) *: p < 0.05 vs. the first quartile using the Mann-Whitney U test Participants were divided into quartiles (Q1-Q4) according to their blood pressures during pregnancy.
