Kaplan-Meier estimates of overall survival of all 55 patients with residual metabolic active areas (n=28) and without residual areas (n=27) on the post-radiotherapy FDG-PET-CT scan. The hazard ratio for death for patients with residual areas compared to individuals without was 2.94 (95% confidence interval: 1.44 to 5.99; p=0.002 by the log-rank test, two-sided).
