  • NOTE: Multivariate modeling based on tumor size, and the three risk group models comparing presence of one high-risk feature (defined as the presence of either decreased CYP2D6 metabolism or a HOXB13/IL17BR gene ratio ≥−1.339) or two high-risk features (defined as the presence of both decreased CYP2D6 metabolism and a HOXB13/IL17BR gene ratio ≥−1.339) relative to CYP2D6 extensive metabolizers with a HOXB13/IL17BR <−1.339 HRs and corresponding 95% CIs.
