  • * β is standardized.

  • Age and treatment intensity are entered as continuous variables to facilitate easier interpretation and to maximize variance of these variables. Thus, positive β values indicate that problems increase with higher age and higher treatment intensity.

  • Dichotomous variables are coded as 0 and 1. In particular, sex is coded as 0 = male, 1 = female and minority status is coded as 0 = white and 1 = minority. Thus, a positive β value for sex indicates a positive relationship between female sex and problem reporting. The negative β value for minority status indicates a positive relationship between being white and report of problems.

  • § Two steps were used in the regression predicting Constitutional/Other problems in order to determine the unique contribution of diagnosis given the multiple categories in this variable.

  • Dummy codes for diagnosis were used to reflect categories of diagnoses of lymphoma and solid tumor.
