Prevention of contamination by xenotropic murine leukemia virus-related virus: susceptibility to alcohol-based disinfectants and environmental stability.
Article in Applied and environmental microbiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Xenotropic murine leukemia virus-related virus (XMRV) represents a novel γ-retrovirus that is capable of infecting human cells and has been classified as a biosafety level 2 (BSL-2) organism. Hence, XMRV represents a potential risk for personnel in laboratories worldwide. Here, we measured the stability of XMRV and its susceptibility to alcohol-based disinfectants. To this end, we exposed an infectious XMRV reporter virus encoding a secretable luciferase to different temperatures, pH values, and disinfectants and infected XMRV-permissive Raji B cells to measure residual viral infectivity. We found that 1 min treatment of XMRV particles at 60°C is sufficient to reduce infectivity by 99.9%. XMRV infectivity was maximal at a neutral pH but was reduced by 86% at pH 4 and 99.9% at pH 10. The common hand and surface disinfectants ethanol and isopropanol as well as the cell fixation reagent paraformaldehyde abrogated XMRV infectivity entirely, as indicated by a reduction of infectivity exceeding 99.99%. Our findings provide evidence of specific means to inactivate XMRV. Their application will help to prevent unintended XMRV contamination of cell cultures in laboratories and minimize the risk for laboratory personnel and health care workers to become infected with this biosafety level 2 organism.
