High-frequency alloreactive T cells augment effector function of low-frequency CD8+ T-cell responses under CD28/CD154 blockade.
Article in Transplantation, 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
backgroundBlockade of costimulatory molecules is a potent method of inducing long-term graft survival. We have previously addressed the issue of donor-reactive T-cell precursor frequency on relative costimulation dependence and found that the presence of a high precursor frequency of donor-reactive CD8 T cells resulted in costimulation blockade-resistant graft rejection, whereas the presence of a low-frequency donor-reactive population did not. To address the mechanisms by which high-frequency T cells obviated the requirement for costimulation, we asked whether a low-frequency population responding concomitantly with a high-frequency response also demonstrated costimulation independence.
methodsA model system was established in which B6 mice containing a low frequency of anti-membrane bound chicken ovalbumin (mOVA) responders and a high frequency of anti-BALB/c responders received a skin graft from B6.mOVAxBALB/c F1 donors in the presence or absence of cytotoxic T-lymphocyte antigen-4 Ig/anti-CD154 costimulatory blockade.
resultsThe results revealed that in the presence of costimulation blockade, high-frequency anti-BALB/c T cells augmented the effector activity of low-frequency anti-mOVA T cells, but it did not enhance the accumulation of anti-mOVA T cells capable of mediating graft rejection.
conclusionsThese results demonstrate that both antigen-specific and antigen-independent factors contribute to the relative costimulation independence of high-frequency T-cell responses.
