MicroRNA-320а as a novel biomarker at preclinical stage of necrotizing enterocolitis in term neonates with congenital heart defects

Figure 2 Correlation heatmap between the plasma microRNA levels and clinical laboratory parameters of term newborns with critical congenital heart defects across the perioperative period. The color scale bars represent nonparametric Spearman correlations. The red color indicates a strong positive correlation, while purple color indicates a strong negative correlation. Only significant correlations are shown (P < 0.05). No necrotizing enterocolitis (NEC)_BS and No-NEC_AS represent newborns without NEC before and after cardiac surgery; NEC_BS and NEC_AS represent newborns, who developed postoperative NEC, before and after cardiac surgery, respectively. CRP: C-reactive protein; MiRs: MicroRNAs; NEC: Necrotizing enterocolitis.
