The P values were determined from comparisons of log10Ep distributions in the different hemoglobin groups using a one-way analysis of variance (ANOVA). The overall comparison of log10Ep distributions for all study participants by hemoglobin type did not show significant differences (P=.86). The mean log10 indicates the mean of individual log transformed parasitemia counts.

Determined using the Kruskal-Wallis ANOVA test.
