Abstract

Context Abacavir, a nucleoside analogue, has demonstrated suppression of human immunodeficiency virus (HIV) replication alone and in combination therapy. However, the role of abacavir in a triple nucleoside combination regimen has not been evaluated against a standard protease inhibitor-containing regimen for initial antiretroviral treatment. Objective To evaluate antiretroviral equivalence and safety of an abacavir-lamivudine-zidovudine regimen compared with an indinavir-lamivudine-zidovudine regimen. Design and setting A multicenter, phase 3, randomized, double-blind trial with an enrollment period from August 1997 to June 1998, with follow-up through 48 weeks at 73 clinical research units in the United States, Canada, Australia, and Europe. Patients Five hundred sixty-two antiretroviral-naive, HIV-infected adults with a plasma HIV RNA level of at least 10 000 copies/mL and a CD4 cell count of at least 100 x 10(6)/L. Interventions Patients were stratified by baseline HIV RNA level and randomly assigned to receive a combination tablet containing 150 mg of lamivudine and 300 mg of zidovudine twice daily plus either 300 mg of abacavir twice daily and indinavir placebo or 800 mg of indinavir every 8 hours daily plus abacavir placebo. After 16 weeks, patients with confirmed HIV RNA levels greater than 400 copies/mL were eligible to continue receiving randomized treatment or receive open-label therapy. Main outcome measure Virologic suppression, defined as HIV RNA concentration o…

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The absolute risk difference is the measure used in the abacavir-indinavir trial.

    “In the former, the interest is in the difference between proportions.This is called the absolute risk difference (ARD) and is the measure used in the abacavir-indinavir trial 1 .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
