Age prevalence profile. Prevalence of AL (a), TT (b), HW (c), SS (d), SM (e), and SH (f) infections plotted against age group mid-point mean. Lower boundary First (25%) quartile, upper boundary third (75%) quartile, inner horizontal line median (50%). The arithmetic mean of each age group is depicted as a grey diamond. n Number of studies used to generate each box (right-hand side of each plot). Prevalence figures higher than the third (75%) quartile are shown as individual points. For abbreviations, see Fig. 2
