Sign., Significance.

a

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.

b

All alleles are 3D7 unless otherwise specified.

c

P values calculated using a Kruskal-Wallis test or χ2 test.

d

Three values are missing for parasitemic status.

e

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.
