Abstract Ninety percent of HIV-1-infected people worldwide harbour non-subtype B variants of HIV-1. Yet knowledge of resistance mutations in non-B HIV-1 and their clinical relevance is limited. Although a few reviews editorials and perspectives have been published alluding to this lack of data among non-B subtypes no systematic review has been performed to date. With this in mind we conducted a systematic review 1996-2008 of all published studies performed on the basis of non-subtype B HIV-1 infections treated with antiretroviral drugs that reported genotype resistance tests. Using an established search string 50 studies were deemed relevant for this review. These studies reported genotyping data from non-B HIV-1 infections that
