Finally, the 180-day phase after infection revealed that a similar correlation trend persisted between IgM and IgG RIs, in spite of sharp correlations between PvCyRPA(T289-G307) and exoerythrocytic peptides for IgM (r = 0.223; p = 0.296) contrasted with weakened correlations between the same peptide and exoerythrocytic counterparts. Here, CD40LG is linked to infection.
