Abbreviations as in Tables 2, 3, and 4. Values of GLS, GCS, GRS and GAS considered as ‘positive’ (sign +) to build the univariate relations in order to homogenize the results of analyses and strengthen their clinical meaning: the higher the values, the better is the strain deformation independent of the plus/minus sign.
