NPPB and ventricular septal defect: Between-group comparisons demonstrated no difference in age (RVIAT: 30.7 ± 21.4 months vs MS: 31.9 ± 27.5 months; P = 0.15, SMD= -0.05), weight (13.0 ± 4.8 kg vs 13.1 ± 6.8 kg; P = 0.72, SMD = −0.014), height (71.5 ± 14.2 cm vs 74.0 ± 19.2; P = 0.68, SMD = 0.02), VSD subtype (P= 0.71, SMD = −0.15), and preoperative NT-proBNP [RVIAT: 91 (IQR, 37.0–177.0) pg/ml vs MS: 86.0 [IQR, 35.0–287.0] pg/ml; P = 0.34, SMD = 0.12).
