ANOVA, analysis of variance. Clonal plasma cells were phenotyped as CD38^brightCD138⁺CD45^−/dimCD19⁻ with light-chain restriction and polyclonal plasma cells were phenotyped as CD38^brightCD138⁺CD45⁺CD19⁺ with polyclonal light chains. Transitional-like B-cells were phenotyped as CD19⁺CD20⁺CD27⁻CD38⁺, plasma blasts were phenotyped as CD19⁺CD20⁺CD27⁺CD38⁺, and memory B-cells were phenotyped as CD19⁺CD20⁺CD27⁺CD38⁻.
