Effect of G6PD activity cut-off criteria on the association analysis of G6PD status and malaria incidence.

<p>NOTE: N, represents the total number of individuals who have a G6PD activity level below the specified cut-off point; RR, relative risk.</p><p>NOTE: Table depicts how the relative risk of malaria varies depending on the cut-off point for determining G6PD deficiency by enzymatic assay.</p>*<p>Sample sizes are too small for meaningful analysis of enzymatically deficient females in these categories.
