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

BACKGROUND/

objectivesHepatic encephalopathy is the common manifestation of decompensated cirrhosis. The association between Helicobacter pylori (H. pylori) infection and hepatic encephalopathy has been shown in many epidemiologic studies. This meta-analysis was conducted to summarize all available studies to estimate the association between H. pylori infection and hepatic encephalopathy.

methodsA comprehensive literature review was conducted using MEDLINE and EMBASE database through March 2017 to identify studies that reported the association between H. pylori infection and hepatic encephalopathy. Effect estimates from the individual study were extracted and combined using random-effect, generic inverse variance method of DerSimonian and Laird.

resultsOf 15,233 studies, eleven studies (four cross-sectional, four case-control, and three cohort studies) met the eligibility criteria and were included in the meta-analysis. The pooled OR of hepatic encephalopathy in patients with H. pylori infection was 1.73 (95% CI 1.09-2.73) when compared with the patients without H. pylori infection. The association between H. pylori and hepatic encephalopathy was not statistically significant after the sensitivity analysis, excluding those using ELISA alone, with a pooled OR of 1.92 (95% CI 0.91-4.05, I

conclusionsThis study demonstrated a potential association between H. pylori infection and risk of hepatic encephalopathy. Future studies are required to assess the effect of chronicity of infection on the development of hepatic encephalopathy.
