Power analysis for the relationship between pre-therapy PET (FMISO and FDG) and patient outcome. FU= length of follow-up; P=power with adjustment for PET confounder; P0=power obtained if confounder not incorporated; PM=effect of 15% measurement error on covariates. Median DFS (first two rows) is 3 years and median OS (last two rows) is assumed to be 6 years.
