Immunolocalization and challenge studies using a recombinant Vibrio cholerae ghost expressing Trypanosoma brucei Ca(2+) ATPase (TBCA2) antigen.
Article in The American journal of tropical medicine and hygiene, 2009. 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
Human African trypanosomiasis is a neglected disease caused by Trypanosoma brucei spp. A parasite cation pump (Ca(2+) ATPase; TBCA2) essential for survival and cation homeostasis was identified and characterized. It was hypothesized that targeting this pump using a Vibrio cholerae ghost (VCG)-based vaccine could protect against murine T. brucei infection. mRNA and protein expression of TBCA2 was differentially expressed in blood and insect stages of parasites and immunolocalized in the pericellular membrane and the flagellar pocket of bloodstream forms. Antigen-specific antibodies and Th1 cytokines, interleukin-2, interferon-gamma, and tumor necrosis factor-alpha were induced in rVCG-TBCA2-immunized mice and in vitro on antigen stimulation of splenic immune T cells, but the corresponding Th2-type response was unremarkable. Despite an increased median survival of 6 days in vaccinated mice, the mice were not protected against infection. Thus, immunization of mice produced robust parasite-specific antibodies but failed to protect mice against parasite challenge.
