  1. °values in bold are statistically significant given our adjusted α of 0.003
  2. aIncludes soft tissue and visceral metastases
  3. bDenominators reflect missing data and thus are not all 125 (D30RT) or 393 (D>30RT)
  4. cPrescribed fractions was not considered in the Bonferroni correction, as this is a decision made by the treating radiation oncologist based on clinical variables
