NOTE. IQR, interquartile range.
a
An AU ≥ 1 was considered a positive response, n = 414.
b
Levels are in arbitrary units (AU), calculated by dividing the optical density (OD) generated by the test sample by the mean OD plus 3 standard deviations of samples from 40 North Americans never exposed to malaria. Median level includes all individuals, including those with a negative response.
