Limitations and Caveats

Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
HIV-1 drug resistance testing and HLA-B*5701 testing were not standard of care during enrollment. EFV and RTV-boosted ATV were open-label, and blinded FTC/TDF vs. ABC/3TC were unblinded in the >=100,000 cp/mL screening viral load stratum Feb 2008.
