Association of the cytokine profile of cerebrospinal fluid with cellularity in aseptic meningitis. The levels of TNF-α and IL-17 as well as cellularity were measured in the CSF as described in material and methods. Graphs of cellularity (x axis) versus cytokine (y axis) were plotted and each dot represents one patient from (top panels) virus not detected (undiagnosed) and (bottom panels) virus-positive meningoencephalitis groups. Dotted lines represent the global median of cellularity (vertical) and cytokine (horizontal) and the percentages express the frequency of patients in each quadrant
