  2. aCombination radiotherapy: combination of EBRT and either radioactive implants or radioisotopes
  3. bUnivariate regression model
  4. cRace was adjusted for in multivariate regression model
  5. NA: not available because no patient died during the study period
  6. Unknown data for adjuvant radiotherapy were not shown in the table
  7. Bold text indicates a significant difference with a p-value less than 0.05 compared to the reference group
