Fig. 4From: 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 elevated levels of ABCB1 gene expression. OS at 60 months in Metformin-treated patients and high levels of ABCB1 expression was analyzed, and metformin had a protective survival benefit (p = 0.025, 95% CI)Back to article page
