Ventricular mass in preterm versus term-born infants. (a) (i) Left and (ii) right ventricular mass index change between birth and 3 months increases with degree of prematurity (P-value relates to one-way ANOVA). (b) Trajectories of (i) left and (ii) right ventricular mass from 15 weeks of gestation through to 3 months of postnatal age for term (red with gray points) and preterm (blue with blue points) infants, and (c) trajectories indexed for head circumference demonstrate the preterm postnatal cardiac hypertrophy. Dashed lines indicate 3rd, 50^th, and 97th centiles. LV indicates left ventricular; RV right ventricular; HC head circumference. **P<0.05; **P<0.01; ^†P<0.001.
