Log-rank test statistics (Mantel-Cox) are given (multiple testing correction by Benjamini-Hochberg) for comparison between the ultra-high risk group (HR-DOD) versus the low risk group (LR-SURV), and between the ultra-high risk group (HR-DOD) and all survivors (LR-SURV and HR-SURV). If a significant association (P < 0.05) was found in a particular stratum (associated with risk factors), this stratum is shown (multiple testing correction for the different comparisons by Benjamini-Hochberg). MYCN = 0: MYCN single copy ; EFS, event-free survival; OS, overall survival. P-values in bold indicate significant associations.
