Fig. 6From: Effect of metformin on the survival of patients with ALL who express high levels of the ABCB1 drug resistance geneGlobal survival (OS) in patients with metformin-treated ALL (metformin users) and ALL without metformin treatment (metformin non-users) with negative ABCB1 gene expression levels. No significant changes were observed in OS in the patients with low ABCB1 gene expression levels (p = 0.048, 95% CI)Back to article page
