Table 4. Mean difference in G6PD activity for Intermediate and High controls by each Biosensor device between Phases A and B.

Low controls were not directly comparable between Phases as these were from different lots.

Device	Intermediate: mean difference in U/gHb*, (95% CI, p)	High: mean difference in U/gHb*, (95% CI, p)
1	-0.1 (-0.1 to 0.2, 0.481)	0.0 (-0.5 to 0.5, 0.993)
2	-0.3 (-0.4 to -0.1, <0.001)	0.1 (-0.3 to 0.5, 0.657)
