Computational intelligence analysis of high-risk neuroblastoma patient health records reveals time to maximum response as one of the most relevant factors for outcome prediction

•Our dataset represents the largest compendium of features for neuroblastoma.•We identified the most relevant predictors of outcome and relapse\progression.•Time to max response to treatment is prognostic and stratifies high-risk patients.•Nine months is the cut-off achieving the largest separation of patients’ survival.•Max response to treatment stratifies clinically relevant subsets of patients.
