Differences in microfilarial prevalence and load between groups. Investigated groups are people who received community-directed doxycycline followed by one or two rounds of annual ivermectin MDA (DOXY + IVM, N = 375) and those who received one or two rounds of annual ivermectin MDA only (IVM, N = 132). A) Difference in microfilaridermia prevalence between groups; the graph shows mean and 95% CI. Fisher's Exact test. B) Difference in microfilarial loads between groups; the graph shows median and 5-95 percentiles of mf/mg of skin in Mf⁺ subjects. Mann-Whitney U test. C) Difference in microfilarial loads in people with palpable nodules (DOXY+IVM, N = 70; IVM, N = 26); the graph shows median and 5-95 percentiles of mf/mg of skin. Mann-Whitney U test.
