GH, growth hormone; IGF-1, insulin-like growth factor 1; LVMi, left ventricular mass index; IVST, interventricular septum thickness; LVFW, left ventricular free wall; RVFW, right ventricular free wall; LVEF, left ventricular ejection fraction; RVEF, right ventricular ejection fraction; ECV, extracellular volume. This indicates that the linear correlation between the CMRi parameter and the clinical data is significant (). ^a indicates a positive linear correlation. ^b indicates a negative linear correlation.
