Comparison of heritability estimates from variance-component (QTDT) and IBS threshold (GCTA-GREML) analysis. MR LV mass, cardiac MRI LVM; ECG LV mass, electrocardiographic LVM; BMI, body mass index; BSA, body surface area. The line-of-identity (i.e. Y = X) is indicated by a dashed line. The QTDT heritability estimate for ECG LVM after adjustment for chest size is shown by a solid triangle.
