Association of dichotomized CD33_PGx6_scores (score of 0 or higher v less than 0; generated using the following six CD33 SNPs: rs12459419, rs1803254, rs35112940, rs2455069, rs61736475, and rs201074739), with response by arm. (A) Differences in disease-free survival by arm in different CD33_PGx6_score groups. (B) Differences relapse risk from end of induction by arm in different CD33_PGx6_score groups.
