Figure 3. — Comparison of received shunt type in freedom from the composite end point of death or cardiac transplantation. Comparison by log-rank test shows no difference with all data considered (P=0.11). Percentage of survival at 1, 6, and 12 years of age by shunt type is shown in the top right quadrant. Hazard ratios (HRs) of right ventricle-to-pulmonary artery shunt (RVPAS) vs modified Blalock-Taussig-Thomas shunt (mBTTS) and CIs during 3 time periods (before stage 2 operation, between stage 2 and Fontan [stage 3], and after Fontan [stage 3]) are compared in the lower left quadrant. Because this analysis was by shunt type received, the 5 participants who had both an RVPAS and mBTTS at the conclusion of the Norwood operation were excluded from this portion of the analysis.
