  1. *Significant at the α = 0.05 level, CI includes 1.00 due to rounding.
  2. **Final model adjusted for age, year of first treatment appointment, place of residence, and treatment clinic disease stage.
  3. ***Prescribed 40 Gy radiation was not included in the final model because it is an intermediate variable between disease stage and radiation completion.
