For the phenotype of parasite density, the effects of antimalarial treatments were addressed by exclusion of density values following 3 wk after treatment (see <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.0030048#s4" target="_blank">Materials and Methods</a>). The phenotype of fever episodes was not corrected for the number of antimalarial treatments because of the direct causal relationship between disease episodes and treatments.</p><p>^§31 weekly regression models.</p><p>^*Anemia (PCV) was normally distributed, Shapiro-Wilk W test, <i>p</i> > 0.2.</p></div

Quantitative-Trait, Multipoint Linkage Analysis of the Key Phenotypes of Uncomplicated Human Malaria

<p>(A and B) Parasitological phenotypes. (C and D) Clinical phenotypes. A 10k-Affymetrix SNP array was used for genotyping 377 individuals comprising 241 siblings of 68 families. Results obtained by NPL are presented in the upper panels (z scores [Z] on the left axis) and those of HE are presented in the lower panels (LOD scores [LOD] on the left axis). Empirical significance levels (<i>p</i>-values indicated by dotted lines) were estimated by 100,000-fold Monte-Carlo permutations.</p
