Stereo-selective binding of monoclonal antibodies to the poly-γ-D-glutamic acid capsular antigen of Bacillus anthracis.
Article in Molecular immunology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Bacillus anthracis is surrounded by an anti-phagocytic capsule that is entirely composed of γ-linked D-glutamic acid (γDPGA). γDPGA is required for virulence and is produced in large quantities following spore germination. We have previously described the isolation of several γDPGA-reactive mAbs. The reagents are effective in both immunoprotection and diagnostic applications. The current work was done to further investigate the specificity of γDPGA-reactive mAbs. The specificity of each mAb was characterized using surface plasmon resonance. Our results indicate that each mAb is stereoselective for binding to D-glutamic acid oligomers, but to varying degrees. In particular, mAb F26G3 is highly selective for γDPGA; alterations in stereochemistry disrupted recognition. These differences in mAb reactivity suggest that binding of γDPGA by mAb F26G3 is more specific than non-directional ionic interactions between a negatively charged antigen and a positively charged antibody.
