Sign., Significance.
For each antigen, represented figures reflect: median value (row 1); [p25–p75] (row 2); and high responders n (%; row 3). High responders are those with absorbance ≥75th percentile.
All alleles are 3D7 unless otherwise specified.
P values calculated using a Kruskal-Wallis test or χ2 test.
Three values are missing for parasitemic status.
For these antigens, insufficient serum volume resulted in missing data for a single child who was aparasitemic and in age group 1–4 yr.
P ≤ 0.05.
