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

Gastric infection by non-Helicobacter pylori Helicobacter (NHPH) species causes gastric disorders, including mucosa-associated lymphoid tissue (MALT) lymphoma. We herein report a dog lover with MALT lymphoma associated with a H. heilmannii sensu stricto infection. H. heilmannii s.s.-associated MALT lymphoma was detected one year after the eradication of H. pylori against lymphoid aggregates. Given that NHPH species colonize the stomachs of cats and dogs, gastric colonization by H. heilmannii s.s. might be involved in the development of MALT lymphoma in this dog lover. Therefore, it is crucial to consider the possibility of gastric infection with NHPH species in cat or dog lovers.
