1 Impact of Patient Characteristics and Anatomy on Results of Norwood Operation for Hypoplastic Left Heart Syndrome  Bahaaldin Alsoufi, MD, Makoto Mori, BS, Scott Gillespie, MS, Brian Schlosser, BS, FASE, Timothy Slesnick, MD, Brian Kogon, MD, Dennis Kim, MD, PhD, Ritu Sachdeva, MBBS, Kirk Kanter, MD  The Annals of Thoracic Surgery  Volume 100, Issue 2, Pages (August 2015) DOI: /j.athoracsur Copyright © 2015 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Competing risks analysis of outcomes after Norwood operation in 219 neonates with hypoplastic left heart syndrome. All patients began alive at Norwood operation and thereafter could transition to one of two mutually exclusive outcomes: death/transplantation or Glenn operation. Solid lines represent parametric point estimates. Dashed lines enclose the 95% confidence interval. (a) Competing hazard functions for each outcome. (b) Proportion of neonates in each of the categories at any given time after Norwood operation.

3 Fig 2 Competing risks analysis of outcomes after Glenn operation in 162 neonates with hypoplastic left heart syndrome. All patients began alive at the Glenn operation and thereafter could transition to one of two mutually exclusive outcomes: death/transplantation or Fontan procedure. Solid lines represent parametric point estimates. Dashed lines enclose the 95% confidence interval. (a) Competing hazard functions for each outcome. (b) Proportion of neonates in each of the categories at any given time after the Glenn operation.

4 Fig 3 (a) Time-dependent survival and (b) risk hazard of death over time after Norwood operation. Solid lines in the parametric model represent parametric point estimates. Dashed lines enclose the 95% confidence interval. Circles represent nonparametric estimates.
