Overview of all radiomics datasets used. Only publicly available datasets were included to allow for easy reproducibility. N denotes the sample size, while d denotes the number of features (corresponding to the dimension of the data). The outcome balance measures the number of events in the outcome. DOI denotes the identifier of the publication corresponding to the dataset
