1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The evolution of drug resistance is a major complication of human immunodeficiency virus type 1 (HIV-1) chemotherapy. HIV-1 reverse transcriptase (RT) is a major target of antiretroviral therapy and ultimately the target of drug resistance mutations. Previous studies have indicated that drug-resistant HIV-1 RTs can alter HIV-1 mutant frequencies. In this study, we have tested a panel of HIV-1 RT variants for their ability to influence virus mutant frequencies. The RT variants tested included drug-resistant RT variants as well as other variants analyzed in enzyme fidelity studies with the lacZalpha gene as a mutation target and/or implicated as being important for enzyme fidelity by structural studies. Combinations of mutations that alone had a statistically significant influence on virus mutant frequencies resulted in different mutant frequency phenotypes. Furthermore, when virus replication occurred in the presence of drugs [e.g., 3'-azido-3'-deoxythymidine, (-)2/,3'-dideoxy-3'-thiacytidine, hydroxyurea, thymidine, or thioguanine] with selected RT variants, virus mutant frequencies increased. Similarly, Vpr variants deficient for binding to the uracil DNA glycosylase repair enzyme were observed to influence HIV-1 virus mutant frequencies when tested alone or in combination with RT variants. In summary, these observations indicate that HIV-1 mutant frequencies can significantly change by single amino acid substitutions in RT and that these effects can be altered by additional mutations in RT, by drugs, and/or by expression of Vpr variants. Such altered virus mutant frequencies could impact HIV-1 dynamics and evolution in small population sizes.
