Figure 1: In paired test, while valsartan increased significantly SD of 24-hour, daytime, and nighttime systolic blood pressure (BP) from baseline, fimasartan reduced significantly SD of 24-hour, daytime, and nighttime of systolic BP from baseline. In comparison with valsartan, fimasartan reduced significantly SD of 24 hours, daytime, and nighttime of systolic BP after 8 weeks.
