IFNB1 and myeloid sarcoma: Comparisons of B cell subsets between the NEDA and EDA groups in IFN-β-treated MS and HCs showed that the percentages of memory B cells, class-switched memory B cells, and non-class-switched B cells were lower in both IFN-β-treated MS groups than in HCs (memory B: NEDA vs. HCs, padj = 0.009; EDA vs. HCs, padj < 0.001; class-switched memory B: NEDA vs. HCs, padj = 0.017; EDA vs. HCs, padj < 0.001; non-class-switched B cells: NEDA vs. HCs, padj = 0.076; EDA vs. HCs, padj = 0.002, Table 6), but the percentages of these memory B cell subsets in the NEDA and EDA groups were comparable.
