Figure 2.

Comparison of levels of immune and inflammatory markers within the cerebrospinal fluis (CSF) in 4 groups of participants: HIV-uninfected (HIV-), primary HIV infection (PHI), chronic infection with CD4 counts ≥200 cells/μL (CHI CD4 ≥200), and chronic infection with CD4 counts <200 cells/μL (CHI CD4 <200). Upper plots indicate median (middle line), interquartile range (extent of boxes), and 10%–90% range (whiskers). Means are denoted with the ‘+.’ Significant differences between PHI participants and other groups are shown. On lower plots, simple linear regression between each CSF marker and days post transmission of sampling are shown with regression lines (solid) and 95% confidence intervals (dotted).
