Change in anti-Plasmodium-falciparum antibody levels. (a) P. falciparum schizont-specific IgM and IgG (optical densities) and (b) antibody levels (IgG) against the merozoite surface proteins MSP-1 (MSP1₁₉) and MSP-2 (Dd2 and CH150) are shown as lines connecting pre- (baseline) and post- (6 weeks) treatment levels for treated and untreated children. Participants who were egg positive at baseline are highlighted in grey thick lines. Stars represent significant difference of mean absorbencies at *P < 0.05 or **P < 0.01.
