Additional file 3:
Clinical patient annotation, summary of clinical characteristics, MSP assays, results and summarized results (per clinical parameter) on the LC480 platform for 89 NB patient samples. Assays differentially methylated between prognostic groups and between neuroblastoma risk factors are discussed in detail, as well as extended analyses on the MSP data (hierarchical clustering (heatmap) and survival analysis according to the number of methylation events (Kaplan-Meier plot)).

Clinical annotation, summary of clinical characteristics, qPCR assays and results of qPCR experiments on 366 NB patient samples (SIOPEN/GPOH cDNA library). Boxplots of the expression levels for CNR1, GRB10, KRT19, PRPH and QPCT in each of the five different NB stages (stages 1, 2, 3, 4 and 4S). A Kaplan-Meier plot shows overall survival according to the relative mRNA expression levels of CNR1, GRB10, KRT19, PRPH and QPCT.
