Figure 1From: Multiplicity of Plasmodium falciparum infection following intermittent preventive treatment in infantsMultiplicity of infection and geometric mean parasite density according to age. Group sizes at ages 3, 6, 9, 12, 15 months: 15, 38, 44, 36, 104. Parasite density declines until 12 months of age and slightly increases thereafter (P = 0.08). IPTi had no effect on parasite density (P = 0.57), at no time (P > 0.4). In multiple, non-parametric ordinal regression analysis, IPTi had no effect on MOI in these children (regression coefficient, -0.33; standard error (SE), 0.33; P = 0.32; age (months), 0.06, SE, 0.06; P = 0.30; log10 parasite density, 0.78, SE, 0.19; P < 0.0001).Back to article page
