Abstract

This article highlights factors that may cause bias in individual controlled trials or meta-analysis of zidovudine (AZT) in HIV disease. The overall benefit of AZT and antiretroviral drug combinations in the progression of HIV disease is probably greater than has been or can ever be shown in an ethical controlled trial.
