Abstract: In a regression model adjusted for CD4+ T-cell count, HIV RNA, year of TCF, age, gender and previous inferior antiretroviral therapy, harbouring > or =9 versus < or =8 mutations was associated with increased mortality (mortality rate ratio [MRR] 2.3 [95% confidence interval (CI) 1.1-4.8]), as were the individual mutations
T215Y (MRR 3.4 [95% CI 1.6-7.0]),
G190A/S (MRR 3.2 [95% CI 1.6-6.6]) and
V82F/A/T/S (MRR 2.5 [95% CI 1.2-5.3]).
