Description of Different Models
| Model no. | Model name | Associated features |
|---|---|---|
| 1 | aaIPI | aaIPI |
| 2 | Consolidation | Chemotherapy regimen, autologous cell transplantation, salvage therapy |
| 3 | Clinical | Age, Ann Arbor stage, ECOG status, number of extranodal sites, LDH |
| 4 | Conventional PET | TMTV, total lesion glycolysis, SUVmax, sDmax |
| 5 | Radiomics PET | Selected RFs after selection step using largest lesion |
| 6 | Consolidation + clinical (models 2 + 3) | All features from clinical and consolidation |
| 7 | Consolidation + clinical + conventional PET (models 2 + 3 + 4) | All features from clinical, conventional (PET), and consolidation |
| 8 | Consolidation + clinical + radiomics PET (models 2 + 3 + 5) | All features from clinical, radiomics (PET), and consolidation |
| 9 | Consolidation + clinical + conventional PET + radiomics PET (models 2 + 3 + 4 + 5) | All features from clinical and conventional (PET), radiomics (PET). and consolidation |
aaIPI = age-adjusted international prognostic index; ECOG = Eastern Cooperative Oncology Group; LDH = lactate dehydrogenase; sDmax = maximum distance between 2 lesions normalized by body surface area.
