Cross-validation estimate of prediction errors: preliminary model: 0.272, the best model: 0.229.

CHD – type of congenital cardiac disease, Ao_X_clamp time – aortic cross-clamp time, DHCA – use of deep hypothermic circulatory arrest, CR – crystalloid cardioplegia, ASD II – atrial septal defect, AVSD – atrioventricular septal defect, AVVI – isolated atrioventricular valve malformations, MIX – other, less frequent cardiac malformations, TGA – all spectrum of transposition of great arteries, ToF – tetralogy of Fallot, UVH – all spectrum of single ventricle disease, including HLHS, VSD – ventricular septal defect, CI – confidence interval.
