A, The geometric mean microfilariae (MF) count per milliliter of blood is shown over time during the first 14 days post-DEC (black circles, dashed line) or post-IVM (open circles, solid line). Geometric mean of 0 indicates that mf were undetectable in all individuals in the group. B, Individual mf counts at baseline and 14 days posttreatment in both groups. *P < .05 between the 2 groups; Mann-Whitney U test (A) and Wilcoxon signed-rank test (B).
