“GINI RE-EVAL” indicates score of a variable in Re-Evaluation models (M_RE^d_τ). “GINI EVAL” indicates score of a variable in Evaluation models (M_E^d_τ). R are potentially reversible or red flag that this person is at risk and needs restorative therapy; Race and Gender variables are included at the bottom of the table for comparison but have very low impact on prediction
