s values from growth competition experiments competing G190S or G190A with K103N in the presence of EFV

	EFV concentration (nM)	s value ± SD
G190A vs. K103N	0	−0.35 ± 0.149
	10	−0.59 ± 0.141a
	50	ND
	100	−0.60 ± 0.052a
G190S vs. K103N	0	−0.61 ± 0.066
	10	−0.49 ± 0.179
	50	−0.31 ± 0.100b
	100	−0.31 ± 0.136b

K103N is the reference strain for calculating all s values.

Data represent an average of 3 independent experiments.

SD, standard deviation.

ND, not determined.

^aP < 0.01, compared to s value for G190A relative to K103N in the absence of EFV, t test.

^bP < 0.01, compared to s value for G190S relative to K103N in the absence of EFV, t test.
