Influence of season, patient age, sex and parasite density on the relative frequencies of msp1 and msp2 allelic families. a Effect of season on the relative frequencies of msp1 and msp2 allelic families. Each color bar represents the relative frequency for each allelic family by season. b Effect of host age (in years) on the relative frequencies of msp1 and msp2 allelic families. Each color line represents a linear relationship fitted to the relative frequency level for each allelic family. c Effect of host sex on the relative frequencies of msp1 and msp2 allelic families. Each color bar represents the relative frequency for each allelic family by sex. d Effect of parasite density on the relative frequencies of msp1 and msp2 allelic families. Each color line represents a linear relationship fitted to the relative frequency level for each allelic family
