Figure 8 Risk-adjusted freedom from reintervention after repair for varying age at complete repair stratified according to major aortopulmonary collateral artery (MAPCA) group. The multivariable equation from the competing risk model was solved twice (for patients with MAPCAs and for those without), each time entering mean values for other predictors. Decreased rates of catheter-based reintervention are illustrated for MAPCA patients when single-stage repair is performed at a later age. Solid lines represent parametric determination of freedom from reintervention for given age at repair; dashed lines enclose 70% confidence intervals.
