Fig. 2

The histograms show the distribution of G6PD activity (U/g Hb); a G6PD activity (U/g Hb) in the study population (male and female) and b G6PD activity (U/g Hb) in individual G6PD genotypes in males. G6PD activity less than 1.73 U/g Hb (< 30% AMM), between 1.73 and 4.04 U/g Hb (30–70% AMM), and more than 4.04 U/g Hb (> 70% AMM) were indicated G6PD deficiency, G6PD intermediate, and G6PD normal, respectively
