Correlation between cytokines in CSF and neurological score (neuro score). A significant negative relationship was seen between the expression of the cytokines IL-5 and IL-6 and neurological disease severity. In each case, the open box on the Y axis shows the average content of each protein in CSF from the HIV-negative controls. Comparison to the control values illustrates that low neurological scores are associated with cytokine increases and higher scores with cytokine decreases
