Tukey HSD analysis of malaria species prevalence by age group. A total of 826, 234 and 368 samples were positive for malaria infection in the age groups ‘young children’ (< 5 years), ‘school children’ (5–16 years) and ‘adults’ (> 16 years), respectively. The total number of samples per group for each species is shown on the X-axis under each bar, and the number of positive samples for each group is shown in each bar. a, b, c Prevalence by age group of P. falciparum (a) P. malariae (b) and P. ovale spp. (c). All comparisons marked with an asterisk were significant at the P < 0.05 level; all other comparisons were statistically non-significant
