Odds ratios (per standard deviation increase) and area under the receiver operating characteristic curve with least absolute shrinkage and selection operator (L1) and ridge (L2) logistic regression models for features from the radiomics signature by Aerts et al.
| Radiomic features | LASSO (L1) | Ridge (L2) |
|---|---|---|
| Energy (first order statistics) | 1.43 | 1.63 |
| Compactness (shape) | 1.28 | 1.45 |
| GrayLevelNonUniformity (GLRLM) | 1.76 | 1.99 |
| GrayLevelNonUniformity (wavelet-HLH) | 1.06 | 1.22 |
| AUC | 0.51 | 0.54 |
AUC: Area under the receiver operating characteristic curve, LASSO: Least absolute shrinkage and selection operator, GLRLM: Gray-level run-length matrix
