Kernel density plots of the distribution of (A) average seated systolic blood pressure (mm Hg), (B) standing systolic blood pressure, and (C) the difference between standing and seated systolic blood pressure (mm Hg) measured during follow-up visits according to initial antihypertensive medication: ramipril (solid line), metoprolol (dash line), or amlodipine (dotted line). There were 19,843 post-randomization visits among participants assigned ramipril, 19,774 post-randomization visits among participants assigned metoprolol, and 9,301 post-randomization visits among participants assigned amlodipine.
