The interplay between the X-DING-CD4, IFN-α and IL-8 gene activity in quiescent and mitogen- or HIV-1-exposed PBMCs from HIV-1 elite controllers, AIDS progressors and HIV-negative controls.
Article in Innate immunity, 2014. 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
X-DING-CD4 blocks HIV-1 long terminal repeat (LTR) and pathogen induced pro-inflammatory response. Increased activity of the X-DING-CD4 gene is associated with cellular resistance to virus; therefore, HIV-1 elite controllers (ECs) should have higher X-DING-CD4 and reduced pro-inflammatory mRNA activity than viremic or uninfected individuals. Also, depending on the cell stimulating factor, expression of X-DING-CD4 mRNA in ECs might be autonomous or contingent on IFN signaling. We compared expression of X-DING-CD4, IFN-α and IL-8 mRNAs in naive, phytohemagglutinin- or HIV-1 exposed PBMCs from ECs, HIV progressors and negative controls; tested correlation between X-DING-CD4 and IFN-α expression; sensitivity of the X-DING-CD4 gene to IFN-α regulation; and evaluated interactions between innate and pro-inflammatory genes. We found that expression of X-DING-CD4 and IFN-α was up-regulated in ECs and correlated in cells stimulated with mitogen, but not HIV-1. The X-DING-CD4 gene was more sensitive to HIV-1 than rIFN-α stimulation. ECs had significantly less IL-8 mRNA when PBMCs were exposed to exogenous HIV-1. Two-way ANOVA showed that control of HIV-1 and virus-induced pro-inflammatory response by ECs stemmed from interactions between expression of innate immunity and pro-inflammatory genes, the state of cell stimulation and the status of virus control. Consequently, interaction of multiple host innate immune responses rather than a single mechanism regulates restriction of HIV-1 in ECs.
