Importance of macrophage inflammatory protein-1α and splenic macrophages in neurodegeneration induced by PVC-211 murine leukemia virus.
Article in Virology, 2011. 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
We recently reported that infection of rats with the neurodegenerative disease-causing retrovirus PVC-211 MuLV results in elevated levels of the chemokine MIP-1α followed by the accumulation of activated microglia in the brain. To investigate the importance of MIP-1α in recruitment of microglia to the brain, we treated rats with MIP-1α antibodies before and after PVC-211 MuLV infection. This caused a delay in the development of paralysis which was associated with a decrease in activated microglia without affecting virus expression. To determine the source of activated microglia, rats were splenectomized 4 days after virus infection. Splenectomized rats showed a delay in disease development that was associated with decreased numbers of activated microglia without affecting virus expression. Together, these results suggest that MIP-1α is directly involved in the neurodegeneration induced in rats by PVC-211 MuLV by recruiting macrophages/microglia from the periphery into regions of the brain that eventually become diseased.
