Table 2. Reference values of the G6PD enzymatic activity profile for the study population, Pailin, Cambodia, 2013.

Reference values	Female	Male	Adjusted male*
Number of cases	487	451	392
Mean (95% CI) UI/g Hb	11.8 (11.4–12.2)	11.2 (10.7–11.7)	12.8 (12.4–13.1)
SD	4.4	5.1	3.3
Median (95% CI) UI/g Hb	11.9	11.7	12.0
IQR	9.7–14.0	10.2–13.4	10.6–13.6
Range	0.5–45.9	0.3–42.5	7.4–42.5

* Adjusted median (100% G6PD activity): an adjusted median value is calculated for which males with severe G6PD deficiency (activity less than 10% normal) have been excluded. This is accomplished by:1. Exclusion of all males with G6PD activity equal to or less than 10% of the male median; 2. Determination of a new median G6PD activity [27].
