Inclusion of Epitopes That Expand High-Avidity CD4+ T Cells Transforms Subprotective Vaccines to Efficacious Immunogens against Virulent Francisella tularensis.
Article in Journal of immunology (Baltimore, Md. : 1950), 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
T cells are the immunological cornerstone in host defense against infections by intracellular bacterial pathogens, such as virulent Francisella tularensis spp. tularensis (Ftt). The general paucity of novel vaccines for Ftt during the past 60 y can, in part, be attributed to the poor understanding of immune parameters required to survive infection. Thus, we developed a strategy utilizing classical immunological tools to elucidate requirements for effective adaptive immune responses directed against Ftt. Following generation of various Francisella strains expressing well-characterized lymphocytic choriomeningitis virus epitopes, we found that survival correlated with persistence of Ag-specific CD4(+) T cells. Function of these cells was confirmed in their ability to more effectively control Ftt replication in vitro. The importance of understanding the Ag-specific response was underscored by our observation that inclusion of an epitope that elicits high-avidity CD4(+) T cells converted a poorly protective vaccine to one that engenders 100% protection. Taken together, these data suggest that improved efficacy of current tularemia vaccine platforms will require targeting appropriate Ag-specific CD4(+) T cell responses and that elucidation of Francisella epitopes that elicit high-avidity CD4(+) T cell responses, specifically in humans, will be required for successful vaccine development.
