Correlation between the clinical signs of visceral leishmaniasis and the cellular versus antibody responses to leishmanial antigen. Data represented in bivariate graphics: (A) the positive correlation between the individual increase of spleen and liver relative weights and the increase in liver parasite load; and (B) the negative correlation between the increase in liver relative weight and the decrease in DTH response to leishmanial antigen, and (C) the increase in liver relative weight and the decrease in anti-NH36 IgG2b antibody response. The results were expressed on graphs as scattering of individual values. R-squared (R2) (coefficients of determination) estimates are shown on graphs. Trend lines were added.
