Kaplan-Meier curve demonstrating freedom from reintervention is 68% (95% CI: 54% to 82%) in patients 55 days of age and younger and 87% (95% CI: 80% to 94%) in patients over 55 days of age (log-rank = 6.21, p = 0.013). (CI = confidence interval; TOF = tetralogy of Fallot.)

3. Fig 2
Freedom from reintervention for patients who underwent elective primary repair of tetralogy of Fallot stratified by TPS. Darkened symbols indicate surgical reintervention, clear symbols reflect percutaneous reintervention. TPS-1 versus TPS-2 (log-rank = 9.4, p = 0.002); TPS-1 versus TPS-3 (log-rank = 64.5, p < 0.001); TPS-2 versus TPS-3 (log-rank = 25.8, p < 0.001); TPS-1 = optimal technical performance; TPS-2 = adequate technical performance; TPS-3 = inadequate technical performance. (CI = confidence interval; TOF = tetralogy of Fallot; TPS = technical performance score.)
