Categorical variables are shown as n (weighted %), continuous variables as means (standard error)
^a The p-value is based on a design-based Rao-Scott F-Test and tests for a potential association between cancer survivor status and the respective demographic, anthropometric or clinical characteristics (available for categorical variables only)
^b includes 12th grade without diploma
^c indicates significant differences in the proportions
^d indicates significant differences in the means
