Value of the Data •A description of which SEP, EEG and brain CT features are relevant for neurological prognostication in CA comatose surviving patients and a description of the statistical analysis. •A statistical analysis including patients with severe disability (CPC 3) in the poor outcome group (a neurological outcome aggregation similar to most of previous published data). This aggregation allows a generalizability of the data. •These data has been derived from a population of patients where withdrawal of life sustaining treatment (WLST) based on prognostication of poor neurological outcome was not performed, except when brain death occurred. •In most of previous prognostication data censoring from WLST, which is often based on the same predictors under investigation, has an important confounding effect.
