ELISA and growth inhibition data for Ngerenya 1998 cohort.

NOTES:*P values calculated using a Chi-squared test or Kruskal-Wallis test.aMedian (25th–75th percentiles).bHigh ELISA responders are those with absorbance≥the 75th percentile.cHigh inhibitors to 3D7 are those with parasite growth less than the approximate median (i.e. dHigh inhibitors to W2mef are those with parasite growth less than the approximate median (i.e. eStrong responders are those with high GIA response to both 3D7 and W2mef. Weak responders are those with low GIA response to both 3D7 and W2mef. Intermediate responders are those remaining.Abbreviations: ELISA, Enzyme-Linked ImmunoSorbent Assay; MSP1 42, Merozoite Surface Protein1 ; GIA, Growth Inhibition Assay. 3D7 and W2mef represent two different parasite lines.
