Study selection criteria and research keywords according to the PICO model.
| Selection criteria | Inclusion criteria | Exclusion criteria | EMBASE search via PICO | MEDLINE/PubMed search via PICO |
| P: population | Adults (age >18 years) affected by nonmetastatic HNSCC (nasopharynx; oral cavity; oropharynx; hypopharynx, larynx; nasal cavity; and paranasal sinus); salivary gland cancer | Pediatric patients (age < 18); non-HNSCC primary tumors; metastatic HNSCC cancer; and diagnosis of cutaneous squamous cell carcinoma or basal cell carcinoma of HNSCC | “Head and neck tumor”/exp OR “head and neck cancer”/exp | Head and neck tumor |
| I: intervention | Radiomics with artificial intelligence; radiomics-based machine-learning methods; and quantative radiographic phenotype analysis | Exclusion of radiomic analysis from the machine-learning method (exclusive analysis of biomarkers, genetic profiles, clinical data, etc.) | “Radiomics”/exp OR “machine learning”/exp | Radiomics OR machine learning |
| C: comparison | (Not explored) | | | |
| O: outcome | Radiation-induced toxicity; radiation-induced toxicity risk | Prediction of survival outcomes; local disease response; prediction of HPV-status or nodal status; and automatic contouring implementation | “Radiation toxicity”/exp OR “radiation tolerance”/exp OR’radiation injury’/exp | Radiation toxicity/radiation tolerance/radiation injury |
