IC₅₀ values for dapsone (DDS) and chlorcycloguanil (CCG) (alone) against K39, ItG2F6, W282 and V1/S strains, obtained from Watkins et al. 1997

Parasite strain	IC50 DDS alone (mg ml−1)	IC50 CCG alone (ng ml−1)	α (SE)	β (SE)
K39	0.013	1.477	8.71 (6.35)	0.23 (0.09)
ItG2F6	0.0055	4.5*	13.65 (1.74)	0.15 (0.02)
W282	0.0128	4.237	38.22 (<0.01)	0.92 (<0.01)
V1/S	0.006	41.95	3.82 (1.20)	0.50 (0.08)

^*Estimate; SE, standard error. α and β are parameter estimates for Equation 1.
