Analysis of the Relationship of β-tubulin Genotype with Patient and Parasitological Independent Variables Before Treatment.

Odds ratios (OR) and 95% confidence intervals (95% CI) for logistic regression of heterozygote status (vs. homozygote) of worms collected before ivermectin treatment on four independent variables. No. females/nod. = total number of females in the nodule; No. nod. 1994 = total number of palpable nodules in 1994; CMFL = Community Microfilarial Load (reference category: 10–40 microfilariae per skin snip (mf/ss)).
