  1. LV, left ventricular. LVM adjusted for significant (P-value < 0.01) covariation in height, treatment-adjusted SBP and DBP and sex, LVM adjusted for significant (P-value < 0.01) covariation in CMR chest lateral diameter, height and treatment-adjusted SBP. *GCTA-GREML models were fitted without “–no-constrain” flag.
