{"denomUnitsSelected":"Participants","description":"Kaplan-Meier plots of EFS and OS will be generated after dichotomization using the median value for the cohort. To determine the prognostic value of NKp30 isoform expression and SNP, univariate analysis will be performed using a log rank test for EFS and OS. In multivariable analysis of EFS and OS, Cox models will be used to test for the independent prognostic ability of NKp30 isoform expression and SNP, adjusting for significant prognostic factors including v-MYC myelocytomatosis viral related oncogene, neuroblastoma derived (avian) (MYCN) status, INSS stage, histology and age at diagnosis.","reportingStatus":"NOT_POSTED","timeFrame":"1 week before first sargramostim injection (day -1 of course 1)","title":"NKp30 Isoform Expression and SNP","type":"OTHER_PRE_SPECIFIED"}
