Breadth of IgG responses to parasite strains stratified by season, Hb type and age.

<p>The number of parasite strains (range, 0-7) recognized by IgG were counted and stratified by season, Hb type and age. <b>a</b>, Tukey whisker plots showing the total number of parasite strains recognized by IgG in paired plasma samples taken before and after the 2009 transmission season. p-values were calculated using Wilcoxon matched-pairs signed rank test. **p<0.01. <b>b</b>, <b>c</b>, Tukey whisker plots showing the total number of parasite strains recognized by IgG before (<b>b</b>) and after (<b>c</b>) the 2009 transmission season, stratified by age and Hb type. p-values were calculated using Kruskal-Wallis test followed by Dunn’s multiple comparison test. *p<0.05, **p<0.01, ***p<0.001.
