The corresponding results of the univariable logistic regression analyses are also shown in Table 1, and associations between the prognostic DNA methylation biomarkers and established prognostic NB risk factors (MYCN amplification, age at diagnosis (both 12 and 18 month cutoff) and International Neuroblastoma Staging System (INSS) stage [19]) are shown in Table 2. This evidence concerns the gene MYCN and neuroblastoma.
