Analysis of the N-terminal positively charged residues of the simian immunodeficiency virus Vif reveals a critical amino acid required for the antagonism of rhesus APOBEC3D, G, and H.
Article in Virology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Previous studies have shown that apolipoprotein B mRNA editing, enzyme catalytic, polypeptide G (APOBEC3G; hA3G) and F (APOBEC3F; hA3F) proteins interact with a nonlinear binding site located at the N-terminal region of the HIV-1 Vif protein. We have analyzed the role of 12 positively charged amino acids of the N-terminal region of the SIV Vif. Simian-human immunodeficiency viruses (SHIV) were constructed that expressed each of these amino acid substitutions. These viruses were examined for replication in the presence of rhesus macaque APOBEC3 proteins (rhA3A-rhA3H), incorporation of the different A3 proteins into virions, and replication in rhesus macaque PBMC. Similar to other studies, we found that K27 was essential for rhA3G activity and rhA3F but was not important for restriction of SHIVΔvif by rhA3A, rhA3D or rhA3H. Our results identified the arginine at position 14 of the SIV Vif as a critical residue for virus restriction by rhA3D, rhA3G and rhA3H.
