a Performance of predictive models built using individual omics data (miRNA/mRNA/protein expression, CNV segment means and DNA methylation). The gray line denotes the performance of the model based only on clinical variables (gender, age, tumor grade and tumor stage). b Performance of predictive models built using individual omics data (miRNA/mRNA/protein expression, CNV segment means and DNA methylation) integrated with clinical data (gender, age, tumor grade and tumor stage). The plots show only the results for the best predictive approach on each omics data, as shown on Fig. 3. The results were validated using 3-fold cross validation. For clarity, the standard errors are omitted here, but are shown in Additional file 6
