Changes in B-Cell Counts and Percentages during Primary HIV Infection Associated with Disease Progression in HIV-Infected Men Who Have Sex with Men: A Preliminary Study

Figure 7

Longitudinal changes of the B-cell counts and percentages in TPs and RPs. Loess curve fitting was applied to this study and performed with SPSS 17.0 software. (a) During HIV infection, TPs (red) in our study had persistently higher B-cell counts than RPs (black). (b) Within 530 days of infection (blue dotted line), TPs had higher B-cell percentages than RPs. Then, B-cell percentages of TPs (red) dropped below those of RPs (black). Loess curve fitting was applied to the study.
