The relationships between age and z-scores of a LVMI (r = 0.300, p < 0.05), b IVSd (r = 0.325, p < 0.05), and c LVPWd (r = 0.379, p < 0.01) in 48 patients with MPS II. The line represents the trendline. The open and closed circles represent mild and severe forms of patients with MPS II, respectively. LVMI, left ventricular mass index; IVSd, interventricular septum thickness in diastole; LVPWd, left ventricular posterior wall thickness in diastole
