The table shows variability between CMR-FT radial strain parameters (Err) and natural radial strain of the LV derived from a short-axis view at rest and with dobutamine stress. 95% Confidence Intervalls of the difference and p-values are given to accurately determine individual variabilities. ErrSAX = left ventricular short-axis radial strain.
