Figure 2. PFS and OS of patients with R-IPI 1-2 according to NCF4 (additive model) and IL10 (dominant model) SNPs (Kaplan-Meier method, log-rank Mantel-Cox test). PFS: Progression-free survival; OS: overall survival; R-IPI: revised International Prognostic Index; SNPs: single nucleotide polymorphisms.
