Kaplan–Meier plots demonstrating differences in patients with high and low primary tumour ¹⁸F-fludeoxyglucose–positron emission tomography coarseness (a–c), contrast (d–f) and busyness (g–i). Differences in overall survival (OS) (a, d and g), progression-free survival (PFS) (b, e and h) and local progression-free survival (LPFS) (c, f and i) are demonstrated. Cum, cumulative.
