Table 2. Adjuvant chemotherapy treatment decisions divided by PREDICT score for patients selected for Oncotype DX (ODX) testing compared to patients not genetically profiled.

*P values relate to Mann-Whitney tests comparing ODX and non-ODX groups; †, data excluded from statistical analysis due to non-positive values in non-ODX group. ODX group, patients with cancers that were genetically profiled through Oncotype DX testing; non-ODX group, patients that did not have Oncotype DX testing.
