Radiomic Profiling of Head and Neck Cancer: ¹⁸F-FDG PET Texture Analysis as Predictor of Patient Survival

Table 2

Univariate model of patients’ clinical data with progression-free survival (PFS) and overall survival (OS). The number of patients is 90 for both PFS and OS, whereas the number of events is 28 and 25, respectively.
