Table 5

% G6PD enzyme activity calculated from the adjusted male median of study participants.

% G6PD activity	A + PD ( = 4)	A + FD ( = 21)	AS + FD ( = 14)	A + N ( = 136)	AS + N ( = 25)
Median (range)	29.41 (19.61–30.39)	15.69 (10.78–25.49)	16.67 (10.78–23.53)	97.06 (49.02–156.9)	108.8 (56.86–137.3)
Mean (95% CI)	27.21 (19.11–35.3)	16.53 (14.63–18.42)	17.23 (14.43–20.02)	99.79 (95.77–103.8)	105.4 (95.82–114.9)

A and S represent haemoglobin A and haemoglobin S, respectively; N: no qualitative red cell G6PD enzyme defect; PD: partial qualitative red cell G6PD enzyme defect; FD: full qualitative red cell G6PD enzyme defect.
