Nonpathogenic CCR2-tropic SIVrcm after serial passage and its effect on SIVmac infection of Indian rhesus macaques.
Article in Virology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
The natural host of SIVrcm is the red-capped mangabey (Cercocebus torquatus torquatus). Although this virus infects macaques and human PBMCs, its pathogenic potential is unknown. We serially passaged SIVrcm through 9 rhesus macaques to assess its potential for virulence. SIVrcm infected all macaques with peak viremia 2 weeks postinfection yet viral loads decreased to undetectable levels about one month after inoculation. Remarkably, SIVrcm replication and virulence did not increase following 7 serial passages. While CD4+ T cells in the gut were decreased in early infection, proportions of memory CD4+CCR5+ T cells were not affected. Three SIVrcm-infected macaques were subsequently challenged with SIVmac251 to assess the potential for superinfection. Interestingly, animals previously infected with SIVrcm had 100 fold lower levels of SIVmac251 in plasma compared to naive animals inoculated with SIVmac251. These results suggest that SIVrcm is nonpathogenic and may be useful for examining effective immune responses in SIV infection.
