Figure 2 Kaplan-Meier survival of CAVB diagnosed during the fetal, neonatal and childhood periods differed significantly between the groups (log-rank; 
2 = 17.2, p = 0.0002). Further analyses using log-rank tests with Bonferroni corrections confirmed the reduced survival rate of the fetal cases (fetal vs. neonatal: 2 = 6.04, p = 0.03; fetal vs. childhood: 2 = 12.3, p = 0.001).
