Survival curves for progression-free survival in diffuse large B-cell lymphoma. The non-germinal center B-like (non-GCB) subtype tended to exhibit shorter progression-free survival (PFS) compared with the GCB subtype (a), whereas a high international prognostic index (IPI) was a significant predictor of shorter PFS (b) in the R-CHOP cohort (n = 43). Low miR-197 levels were also associated with shorter PFS in the full cohort (n = 51) (c) and its non-GCB subgroup (n = 37) (d) as well as the R-CHOP cohort (n = 43) (e) and its non-GCB subgroup (n = 31) (f)
