Fig 2. Human IgG4 response against native AsHb is reduced by MDA intervention.

Fig 2

Plasma samples were analyzed at baseline (2002), after two years of MDA (2004), at the end of the trial, prior to the final MDA (2007), and 2 years after the end of the trial (2009). Antibody reactivity decreased significantly after MDA. The lines connect plasma samples from the same individuals collected in different years of the study. The red dotted line represents the OD cutoff of 0.380 (* P < 0.05, ** P < 0.01, *** P < 0.001).
