To the Editor: Dr Gallant and colleagues1 compared the proportion of patients with HIV RNA levels less than 400 copies/mL at week 48 in antiretroviral-naive patients who randomly received either tenofovir or stavudine, in combination with efavirenz and lamivudine. The authors stated in their methods that “the study was designed as a noninferiority trial (ie, equivalence).” However, noninferiority and equivalence hypotheses are not identical.
