Figure 2. Workload and Oxygen Consumption (V̇o₂) at Peak Exercise and Its Association With Left Ventricular (LV) Mass and Biventricular Remodeling Score in the Study Populations.

A, Regression line showing a positive association between the peak V̇o₂ and the indexed LV mass (ρ = 0.7934; P < .001, and P = .046 when adjusted by age, sex, and body surface area). Adults born small for gestational age (SGA) present a significantly different regression line and have lower exercise capacity per unit of LV mass than controls (P = .04 for interaction). B, Regression line showing an inverse association between the peak V̇o₂ and the quantity of biventricular remodeling score by 3-dimensional shape analysis (ρ = −0.2549; P = .009, and P = .002 when adjusted by age, sex, and body surface area).
