Prognostic significance of the subgroups based on gene expression profiles of BMMNCs. (A) A schematic depicts how to construct a logistic regression model to predict the subgroups using 10-fold cross-validation on gene expression data. (B) A table shows gene names and their coefficients in a logistic regression model to predict the subgroups based on gene expression profile of BMMNCs. (C) Rates of overall survival in the 2 subgroups for the test set of BMMNC samples. (D) Cumulative incidence of leukemic transformation in the 2 subgroups for the test set of BMMNC samples. The patients who had already developed leukemia at the time of sampling were removed from the analysis.
