By comparative analysis, we found that both the AST/ALT ≤ 1.5 and AST/ALT ≤ 2.0 groups might appear to have a better prognosis than the AST/ALT>1.5 and AST/ALT>2.0 groups (Supplementary Figures 1B, C), partly suggesting the important role of AST and ALT in DLBCL. This evidence concerns the gene GPT and diffuse large B-cell lymphoma.
