1 · What the graph read from it

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.

2 · The registry

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

Helicobacter pylori infection in the stomach is a common cause of peptic ulcer disease and is a strong risk factor for the development of gastric adenocarcinoma, yet no effective vaccine against H. pylori infection is available to date. In mice, mucosal vaccination with H. pylori antigens when given together with cholera toxin (CT) adjuvant, but not without adjuvant, can induce protective immune responses against H. pylori infection. However, the toxicity of CT precludes its use as a mucosal adjuvant in humans. We evaluated a recently developed, essentially nontoxic double mutant Escherichia coli heat-labile toxin, LT(R192G/L211A) (dmLT), as a mucosal adjuvant in an experimental H. pylori vaccine and compared it to CT in promoting immune responses and protection against H. pylori infection in mice. Immunization via the sublingual or intragastric route with H. pylori lysate antigens and dmLT resulted in a significant decrease in bacterial load after challenge compared to that in unimmunized infection controls and to the same extent as when using CT as an adjuvant. Cellular immune responses in the sublingually immunized mice known to correlate with protection were also fully comparable when using dmLT and CT as adjuvants, resulting in enhanced in vitro proliferative and cytokine responses from spleen and mesenteric lymph node cells to H. pylori antigens. Our results suggest that dmLT is an attractive adjuvant for inclusion in a mucosal vaccine against H. pylori infection.
