↵* Logistic regression was used to assess factors affecting proportion of individual plans agreeing with subsequent claims. Factor categories assessed were age (<75, >75 y), performance status (0, 1, ≥2), comorbidity (0, 1 or 2, 3+), cancer type (bladder, ovarian, pancreatic, SCL, stomach), provider specialty (medical oncology, gynecology, internal medicine, radiation oncology, surgery, and other), and pre-PET plan (image, biopsy, treatment, watch). On basis of logistic regression model, adjusted percentage agreements were calculated for each category and range calculated.
