Figure 2 Percentage of participants developing a depressed left ventricular ejection fraction by baseline quartile of left ventricular mass (LVM) (A) and LVM indexed to body surface area (BSA) (B) or height (C). Baseline LVM was assessed by echocardiography or electrocardiography (ECG). P < 0.001 for the association of LVM irrespective of indexation method with incident depressed ejection fraction in all cases. White bars = quartile 1; bars with horizontal lines = quartile 2; bars with diagonal lines = quartile 3; black bars = quartile 4. Quartiles of echocardiographic LVM (g):  114.7, 114.8 to 137.2, 137.4 to 165.7, >165.7, respectively. Quartiles of electrocardiographic LVM (g): <128.1, 128.1 to 145.4, 145.43 to 167.2, and >167.2, respectively. Quartiles of echocardiographic LVM/BSA (g/m2): 67.7, 67.8 to 79.2, 79.3 to 93.5, and >93.5, respectively. Quartiles of electrocardiographic LVM/BSA (g/m2): <76.9, 76.9 to 83, 83.1 to 90.3, and >90.3, respectively. Quartiles of echocardiographic LVM/height (g/m): 70.40, 70.42 to 84.13, 84.14 to 99.97, and >99.97, respectively. Quartiles of electrocardiographic LVM/height (g/m): 79.48, 79.49 to 88.51, 88.52 to 99.49, and >99.49, respectively.
