The bolded values signifies statistical significance (i.e. p < 0.05) between pre-CT and post-CT values.
Using the Reg procedure, a stepwise multiple regression with forward entry method was applied where the outcome variable (baseline analyte level) was regressed against multi viatmin intake (yes, no) or radiation history as possible predictors.
