LVMI left-ventricular mass index, LVIDd left-ventricular internal diameter at end-diastole index, PWTd left-ventricular posterior wall thickness at end-diastole, SWTd septal wall thickness at end-diastole, 95 % CI 95 % confidence interval
*p-value of the multiplicative interaction of the SLI with considered BMI classes
^aadjusted for age and sex only
^bBeta gives the increase of the respective echocardiographic parameter per mV increase of the SLI
