High-level, lasting antiviral immunity induced by a bimodal AIDS vaccine and boosted by live-virus exposure: prevention of viremia.
Article in AIDS (London, England), 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo characterize the correlates of protection from systemic infection in a vaccinated rhesus macaque, RAt-9, which had been challenged sequentially with two related clade C simian/human immunodeficiency viruses (SHIV-Cs) yet remained aviremic for more than 5 years despite indirect evidence of cryptic infection.
designTo measure long-term anti-SHIV-C immunity, host genetics and gene-expression patterns for protective correlates.
methodsLong-term immune reactivity was evaluated and identification of virus in RAt-9 was attempted by RT-PCR analysis of concentrated plasma and blood transfer to CD8(+) cell-depleted infant macaques. Full MHC genotyping of RAt-9, TRIM5α and KIR3DL allelic expression analysis of PBMC, and microarray gene expression analysis were performed.
resultsAll attempts to detect/isolate virus, including blood transfer to CD8(+) cell-depleted infant rhesus macaques, were negative, and the animal maintained normal levels of memory CD4(+) T cells in both peripheral blood and gut tissues. However, RAt-9 maintained high levels of anti-SHIV-C humoral and cellular immunity, including reactivity to nonvaccine neoantigens (Nef and Rev), up to 63 months postinitial challenge, suggesting chronic sub-threshold infection. RAt-9 expressed the Mamu A*001 allele negative for B*008 and B*017, had a B13 serotype, and had increased expression of killer-cell immunoglobulin-like receptors (KIRs) previously linked to favorable outcomes of lentiviral infection. Elements of the gene expression profiling coincided with genotyping results. RAt-9 also displayed CD8 cell noncytotoxic antiviral response (CNAR) activity.
conclusionMonkey RAt-9 is the first example of a virus-exposed, persistently aviremic animal that has maintained long-term, high-level cellular and humoral antiviral immunity in the absence of an identifiable cryptic reservoir.
