Table 4. Comparison of drug-resistant effects between reported mutations selected in this study and those in HIV drug resistance database of Stanford University.

Drug	Mutations	Level of resistance (increased folds of EC₅₀)
		In this study	In HIV drug resistance database of Stanford University
NVP	A98G	M (17)	L (2–3)
	V106M	H (22–32)	H (70)
	V108I	L (3)	L (UD)
	Y181C	H (450)	H (123)
	K238N	L	Unknown

H: high level of resistance (Fold change (FC)>20); M: medium level of resistance (20>FC>4); L: low level of resistance (FC<4). UD: undetected. They were defined according to Stanford database http://hivdb.stanford.edu/cgi-bin/Marvel.cgi.
