Fig. 3

Baseline nighttime blood pressure. Nighttime systolic blood pressure (SBP) is shown on graph-a and nighttime diastolic blood pressure (DBP) on graph-b. Open circles, control (soy food) group; closed circles, miso group. Values are expressed as the mean±standard deviation. Differences in blood pressure between time points in each group and between the groups were analyzed using one-way analysis of variance and Student’s t-test, respectively. *P < 0.05, **P < 0.001, ***P < 0.0001. aDifferences in BP profile during the whole night were assessed by repeated measures analysis of variance. Ns, not significant
