Changes in function of HIV-specific T-cell responses with increasing time from infection.
Article in Viral immunology, 2010. 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
Recently HIV-infected individuals have virus-specific responses characterized by IFN-gamma/IL-2 secretion and proliferation rarely seen in chronic infection. To investigate the timing of loss of HIV-specific T-cell function, we screened cells from 59 treatment-naïve HIV-infected individuals with known dates of infection for proteome-wide responses secreting IFN-gamma/IL-2 and IFN-gamma alone by ELISPOT. HIV peptide-specific proliferation was assessed by carboxyfluorescein diacetate succinimidyl ester (CFSE) dilution. The contribution of IFN-gamma/IL-2 and IFN-gamma-only secretion to the total HIV-specific response was compared in subjects infected <6, 6-12, and 12-36 mo earlier. The frequency of IFN-gamma/IL-2-secreting cells fell, while that of IFN-gamma-only secretion rose with time from infection. HIV peptide-specific proliferative responses were almost exclusively mediated by CD8(+) T cells, and were significantly lower in cells obtained from the 12-36 mo versus < 6 mo post-infection groups. By the second year of infection there was a significant difference in these functions compared to those assessed within 6 mo.
