There was a significantly negative correlation (rs = −0.39, n = 40, p = 0.021) between Na intensity and CCL11 levels in the group infected with only Na. In contrast, although insignificant, there was a trend of positive correlation (rs = 0.11, n = 40, p = 0.45) between Na infection intensity and CCL11 levels in the group with Na/Pf co-infection. The gene discussed is CCL11; the disease is infection.
