Figure 3: Comparison of answers from survey participants using NA (n = 10) versus those using HDCs (n = 44). The group using NA includes 2 participants using both NA and TTO. Participants used an 11-point scale from 0 to 10 to rank (a) severity of disease before helminthic therapy (but after standard medical therapy), (b) effectiveness of prior medical treatment, (c) effectiveness of helminths at treating disease symptoms, (d) their legal concerns regarding helminthic therapy, (e) and the side effects of helminthic therapy. The data reveal a number of differences between survey participants using NA versus those using HDCs; comparisons were all statistically significant except comparison of the effectiveness of the helminths at treating disease.
