NMDS ordination of the Mali samples on the basis of P. falciparum infection status at the end of the 6-month dry season. Samples from subjects with persistent, asymptomatic P. falciparum infection at the end of the dry season fall into two components PP1 (orange) and PP2 (red); samples from P. falciparum-uninfected subjects fall into two components as well – PN1 (cyan) and PN2 (blue). The mean vector of each component is labeled with an asterisk in their respective color. The average ages for the groups are 3.2 years (PP1), 13.6 years (PP2), 1.3 years (PN1) and 9.2 years (PN2)
