We compared the AICs and AUCs using the second dataset in the 8 models: NULL (without parameter), “UGT1A1*6 or *28” (an integrated predictive factor based on polymorphisms related to neutropenia), and rs9351963 (genotype of rs9351963 in KCNQ5), Amrubicin, MMC, rs9351963+Amrubicin, rs9351963+MMC, and rs9351963+Amrubicin+MMC (Fig. 4A). Here, UGT1A1 is linked to neutropenia.
