  1. The covariates age, gender, education, income, comorbidities and time since diagnosis was included in all analyses
  2. aThe predicted absolute values on their original scale (i.e. the model predicts that never married patients spend 104 days at home). These can be used to estimate the average value for the married and previously married. E.g. the predicted number of days Married patients spent at home was 135.09 (104.68 + 30.42)
