Identification and molecular characterization of SIV Vpr R50G mutation associated with long term survival in SIV-infected morphine dependent and control macaques.
Article in Virology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Viral protein R (Vpr) is an accessory protein of HIV and SIV involved in the pathogenesis of viral infection. In this study, we monitored SIV evolution in the central nervous system and other organs from morphine-dependent and control animals by sequencing vpr in an attempt to understand the relationship between drug abuse, disease progression, and compartmentalization of viral evolution. Animals in the morphine group developed accelerated disease and died within twenty weeks post-infection. A unique mutation, R50G, was identified in the macaques that survived regardless of morphine exposure. Functional studies revealed that the R50G mutation exhibited altered cellular localization and decreased the expression levels of both IL-6 and IL-8. Our results, therefore, suggest that sequence changes within the SIV/17E-Fr vpr occur regardless of drug abuse but correlate with survival, and that they alter disease progression rates by affecting Vpr functions.
