Mean percent decrease (95% CI) in microfilaremia levels at 6, 12, and 24 months after treatment for the 2 treatment arms, as determined by microfilaria (Mf) counts at each time point divided by baseline Mf count for each participant. The numbers of participants for each time point are shown in Table 2. Participants without detectable Mf are included in the analysis and considered to have 100% clearance. ***P < .001 using Mann–Whitney test (2-sided) comparing individuals at 6 and 12 months. Abbreviations: ALB, albendazole; CI, confidence interval; DEC, diethylcarbamazine; IVM, ivermectin; Mf, microfilaria.
