Figure 6.

Lymphocyte subset analysis following single-dose administration of diethylcarbamazine (DEC) or ivermectin (IVM). Percentages of baseline CD3⁺CD4⁺, CD3⁺CD4⁺CD25⁺, CD3⁺CD8⁺, and CD3⁺TCRγδ⁺ in peripheral blood measured at day 1 and day 3 posttreatment. Data for individual subjects who received DEC are denoted by black circles and dashed lines and those who received IVM by open circles and solid lines. The gray areas indicate a decrease from baseline values. *P < .05, Wilcoxon signed-rank test.
