Age was measured on a continuous scale therefore the Pearson correlation coefficient was used to assess those correlations with the PedsQL scores. Income was measured as ordinal categories thus the association of income with each of the PedsQL scores was assessed by the multiple correlation (R) of the categories as a set of variables with each score.
