Kaplan-Meier survival curves for patients with high (▴) and normal (▪) CD86 expression in various cell subpopulations.
(A) Mature plasma cell subpopulations (high CD86 greater than 60%). (B) Primitive plasma cell subpopulations (high CD86 greater than 81%). Only the mature plasma cells showed a significant difference in the prognostic importance of CD86 expression (χ2 = 7.6;P < .006).
