Riboflavin transporter: evidence of a role as entry receptor for chimpanzee endogenous retrovirus.

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
Endogenous retroviruses (ERVs) are remnants of ancestral viral infections in germ cells that constitute a substantial proportion of the mammalian genome and are assumed to provide molecular fossil records of ancient infections. Analysis of these sequences may reveal the mechanisms of virus-host co-evolution, viral endogenization, and extinction. Chimpanzee endogenous retrovirus 1 (CERV1), a gamma retrovirus, is estimated to have circulated within primates for ~10 million years, although it is now apparently extinct. In this study, we aimed to gain an understanding of how the extinct CERV1 was transmitted and endogenized. On the basis of the identification of CERV1 fossils in the primate genome and using the expression-cloning method with the human cDNA library, we found that riboflavin transporter human SLC52A2 served as a receptor for CERV1 entry. The ectopic expression of human and chimpanzee SLC52A2 and its related SLC52A1 in heterogenic cells confers susceptibility to infection by CERV1 and porcine endogenous retrovirus (PERV). Virus interference experiments have shown that CERV1 inhibits infection by PERV and
