Clinical characteristics correlated with immunological parameters from cutaneous leishmaniasis patients. Correlation between the percentage of effector CD8+ T-lymphocytes (A, B, C) and apoptotic-effector CD8+ T-lymphocytes (D, E, F) with diameter of lesion (mm). (A, D) PBT - patients before treatment (n = 8); (B, E) PDT – patients during treatment (n = 14); (C, F) PAT - patients after treatment (n = 11). The graphics show fit lines with confidence curves. Statistical analyses were performed by Spearman’s correlation test. Results were considered significant with P < 0.05.
