FOXD3 and neuroblastoma: Kaplan–Meier survival plots of 88 well-defined NB cases derived from R2 microarray analysis and visualization platform revealed that patients with high FOXD3 (P = 1.8 × 10−7) or NDRG1 (P = 4.1 × 10−4) expression had greater survival probability than those with low expression (Figure 1E).
