  1. Abbreviations: BNP, B-type natriuretic peptide; CI, confidence interval; FS, fractional shortening; LVO, left ventricular output; NTproBNP, N-terminal pro-BNP; PDA, patent ductus arteriosus; RVO, right ventricular output; SVC, superior vena cava.
  2. aMultiple regression includes correction for hour of life at study and the size of PDA.
