FIGURE 3.  Kaplan–Meier survival curves of NSCLC patients with high tumor SUV (weight-corrected mean SUV_T > 10) on ¹⁸F-FDG PET vs. patients with less active primary tumors. Median survival of patients with elevated SUV_T was significantly shorter (227 vs. 874 d; P = 0.003, log-rank test). T = primary tumor.
