Acquisition of IgG antibodies against the N-terminus of Pv-MSP1. (A) Comparison of median of IgG anti ICB25 of the three minor groups is shown by one-way non-parametric Kruskal-Wallis test. (B) The mean level of IgG anti-ICB2-5 using non-parametric Dunn’s test for multiple comparisons. Statistically differences in the mean antibody at p < 0.05 is shown as letters “a” or “b”. Intermediate level of antibodies is shown as “ab”.
