  • a The mean IC50 of each drug, standard deviation (SD; derived from 13 independent determinations), and 95% confidence interval (CI; derived from 13 independent determinations) are listed for drug-sensitive (strain CNDO) and multidrug-resistant (strain R268) reference viruses. The multidrug-resistant reference virus contains RT mutations M41L, D67N, K103N, M184V, L210W, T215Y, and K219Q and PR mutations L10I, M36I, L63P, A71V, and V82T.
