Fig. 3From: Quantitative trait locus analysis of parasite density reveals that HbS gene carriage protects severe malaria patients against Plasmodium falciparum hyperparasitaemiaParasitaemia distribution stratified by HbS genotype. Plot represents parasite densities in all malaria patients (n = 288). HbS genotypes are represented heterozygous (AT) and non-carriers (AA). Parasite density represents the number of parasitized erythrocytes/microscopic field. Data are represented in boxes that include 50 % of sample distributions (2nd and 3rd quartiles) with horizontal lines (median) and outliers are represented by circles Back to article page
