From: Pre-radiotherapy FDG PET predicts radiation pneumonitis in lung cancer
Kaplan-Meier curves for pre-treatment SUV 95 . Time to radiation pneumonitis symptoms is compared among subsets of patients within observed terciles of SUV95 (SUV95 < 0.99, 0.99 ≤ SUV95 < 1.2, SUV95 ≥ 1.2). Right-censored observations are marked by +. The hazard ratios (HR) and corresponding 95% confidence intervals for comparing between the (2nd and 1st) terciles; and (3rd and 1st) terciles follow as 2.25 (1.12, 4.52) and 2.39 (1.19, 4.82), respectively. Median time to symptoms for patients with SUV95 ≥ 0.99 was 101 days.
