Competition within the virus-specific CD4 T-cell pool limits the T follicular helper response after influenza infection.
Article in Immunology and cell biology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
CD4 T follicular helper cells (TFH) are critical in the generation of potent and long-lived B-cell responses after viral infection. However, the factors that dictate the generation and maintenance of these cells are not fully understood. Here we use adoptive transfer of OTII T-cell receptor transgenic CD4 T cells, followed by infection with recombinant influenza A virus (IAV), as a means of identifying and tracking virus-specific CD4(+) T-cell responses. We show that T-cell competition within the virus-specific CD4 T-cell pool induced by IAV infection limits the proliferation and differentiation of IAV-specific CD4(+) TFH responses. In particular, increased T-cell competition for antigen results in a diminished IAV-specific TFH CD4 T-cell responses, particularly germinal center TFH responses. Strikingly, competition in the form of preexisting cellular immunity generated by heterosubtypic IAV immunization limits de novo CD4 T-cell responses in secondary lymphoid tissue. Taken together, these data show a profound linkage between antigen availability and promotion of TFH CD4(+) T-cell responses in response to infection. These data suggest that competition within the CD4 T-cell pool limits TFH responses and may be an important regulatory mechanism for controlling immunity.
