  1. Only the features with significant FDR-adjusted p values at multivariate analysis
  2. *HH filter
  3. °In the model with VoxelVolume as the dependent variable, clinical volume was not used as independent predictor. FBP filtered backprojection, FDR false discovery rate, IR iterative reconstruction
