  1. Ref. reference.
  2. The final result of a multivariable Cox analysis with backward elimination of the nonsignificant variables. The initial model included the following variables: CCNF (Cp = 7.884), tumor grade, and TNM stage. HR is shown for the subgroup marked in bold.
  3. n case number, EPV events per variable.
