PfHRP2 levels and parasite density: variation of the median optical density (OD) for PfHRP2 detection by ELISA in cord blood according to parasite density levels in cord, maternal peripheral and placental blood by qPCR. Parasite densities were categorized using interquartile ranges (IQR) as follows: 1 = negative; 2 = 0 to IQR1; 3 = IQR1 to IQR2; 4 = IQR2 to IQR3 and 5 = IQR3 to the maximum; KW, Kruskal Wallis coefficient.
