Linear regression and Bland-Altman analyses demonstrating levels of correlation and agreement between regional end-systolic strains calculated by 2D STE and sonomicrometry: a, b radial strains, c, d circumferential strains. P-values on Bland-Altman plots refer to differences of observed mean differences from zero and were calculated via a single sample t-test
