GANP interacts with APOBEC3G and facilitates its encapsidation into the virions to reduce HIV-1 infectivity.
Article in Journal of immunology (Baltimore, Md. : 1950), 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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 ssDNA-dependent deoxycytidine deaminase apolipoprotein B mRNA-editing, enzyme-catalytic, polypeptide-like 3G (A3G) is a potent restrictive factor against HIV-1 virus lacking viral-encoded infectivity factor (Vif) in CD4(+) T cells. A3G antiretroviral activity requires its encapsulation into HIV-1 virions. In this study, we show that germinal center-associated nuclear protein (GANP) is induced in activated CD4(+) T cells and physically interacts with A3G. Overexpression of GANP augments the A3G encapsidation into the virion-like particles and ΔVif HIV-1 virions. GANP is encapsidated in HIV-1 virion and modulates A3G packaging into the cores together with cellular RNAs, including 7SL RNA, and with unspliced HIV-1 genomic RNA. GANP upregulation leads to a significant increase in A3G-catalyzed G→A hypermutation in the viral genome and suppression of HIV-1 infectivity in a single-round viral infection assay. Conversely, GANP knockdown caused a marked increase in HIV-1 infectivity in a multiple-round infection assay. The data suggest that GANP is a cellular factor that facilitates A3G encapsidation into HIV-1 virions to inhibit viral infectivity.
