Involvement of antigen-presenting cells in the enhancement of the in vitro antibody responses by cholera toxin B subunit.
Article in Immunology, 1992. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The enhancing effect of cholera toxin B subunit (CTB) on primary antibody responses to keyhole limpet haemocyanin (KLH) and the cellular basis of the effect were investigated, using in vitro cultures of mouse spleen cells. CTB (1-100 ng/ml) enhanced anti-KLH IgM, IgG and IgA antibody responses in a dose-dependent manner, when added to the cultures with KLH. This immunoenhancement was antigen specific, but not due to either polyclonal activation of the spleen cells or antigenic cross-reactivity between CTB and KLH. CTB did not affect the kinetics of the anti-KLH antibody responses. Early (Days 0-1) addition of CTB to the cultures enhanced the anti-KLH antibody production, whereas late (Days 5-7) addition of CTB did not. Addition of CTB with KLH to splenic adherent cells (SAC) resulted in a dose-dependent enhancement of the anti-KLH antibody responses, when the SAC were reconstituted with unimmunized non-adherent cells. Moreover, CTB enhanced IL-1 secretion from SAC incubated with KLH. These results suggest that CTB enhances the primary anti-KLH antibody responses in vitro by acting on early events in the responses, and that antigen-presenting cells play a major role in the enhancement.
