Fig. 2From: Prognostic value of perioperative NT-proBNP after corrective surgery for pediatric congenital heart defectsComparisons of postoperative changes of NT-proBNP ratios over time between two clusters by Gaussian mixture clustering model. Red solid line represents mean of slowly rising group. Blue solid line represents mean of fast rising group. Semi-transparant lines represents ratio of NT-proBNP levels in every children with CHD undergoing cardiac surgery. The scale of y axis is log transformedBack to article page
