Figure 2: In paired test, while valsartan increased significantly 24-hour CV of systolic and diastolic blood pressure (BP) and 24-hour wSD of systolic BP from the baseline after 8 weeks, fimasartan reduced significantly 24-hour wSD of systolic BP from the baseline after 8 weeks. Comparing with valsartan, fimasartan reduced significantly 24-hour wSD and ARV of systolic BP after 8 weeks.
