a. Estimated Change in ARz by Baseline Aortic-Root Elastic Modulus
Estimated change in maximum aortic-root z-score (ARz) with pointwise 95%
confidence bands, for at or below median (blue) vs. above median (red) baseline
aortic-root elastic modulus groups. AR = aortic root.
b. Estimated Change in ARz by Baseline Heart Rate-Corrected Aortic-Root
Stiffness Index. Estimated change in maximum aortic-root z-score
(ARz) with pointwise 95% confidence bands, for at or below median (blue)
vs. above median (red) baseline heart rate-corrected aortic-root stiffness index
groups. AR = aortic-root; sqrt = square root
