Escape variants of the XPR1 gammaretrovirus receptor are rare due to reliance on a splice donor site and a short hypervariable loop.
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
Entry determinants in the XPR1 receptor for the xenotropic/polytropic mouse leukemia viruses (XP-MLVs) lie in its third and fourth putative extracellular loops (ECLs). The critical ECL3 receptor determinant overlies a splice donor and is evolutionarily conserved in vertebrate XPR1 genes; 2 of the 3 rare replacement mutations at this site destroy this receptor determinant. The 13 residue ECL4 is hypervariable, and replacement mutations carrying an intact ECL3 site alter but do not abolish receptor activity, including replacement of the entire loop with that of a jellyfish (Cnidaria) XPR1. Because ECL4 deletions are found in all X-MLV-infected Mus subspecies, we deleted each ECL4 residue to determine if deletion-associated restriction is residue-specific or is effected by loop size. All deletions influence receptor function, although different deletions affect different XP-MLVs. Thus, receptor usage of a constrained splice site and a loop that tolerates mutations severely limits the likelihood of host escape mutations.
