Estimated trends in 1-year relative survival for patients with metastatic non-small cell lung cancer in subpopulations defined by: (A) age at diagnosis, (B) sex, (C) race, (D) prevalent smoking in the patient’s county of residence (dichotomized at median), (E) prevalent poverty in the patient’s county of residence (dichotomized at median). Point estimates, observed values in 2000 and 2010, and fitted trends from log-linear models (lines) are shown. Rates in panels (B-E) are age-standardized. P_par: P value from the test of slope parallelism.
