Predictors of the adults and children who would have the top 5% and 10% of subsequent (2010) costs using quantile regression.

Each model had only a single independent variable controlling for age, gender and mental health diagnosis.

t indicates the strength of the association and the p value the statistical significance. R² is the explained variance, that is, the extent to which the prior year variables predict subsequent year costs; the higher the R², the greater the explanatory or predictive power.
