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

Since numerous studies have stated that there may be a relationship between Helicobacter pylori infection and nonalcoholic fatty liver disease, and because of the high prevalence of both conditions worldwide, this study investigated the risk of non-alcoholic fatty liver disease in patients infected with H. pylori. Following a systematic review of PubMed, Scopus, Web of Science and Embase, and a search in Google Scholar using MeSH terms such as H. pylori and non-alcoholic fatty liver disease, the relevant papers up to November 2020 were reviewed. All cohort, case-control, and cross-sectional studies that examined the risk of developing non-alcoholic fatty liver disease in patients infected with H. pylori entered this study. A meta-analysis was conducted in STATA 11. This systematic review examined 22 papers with 117 117 participants (33 711 patients infected with H. pylori and 83 406 participants as control) and 20 studies were subjected to meta-analysis The results indicated a 22% to 27% increase in the risk of developing non-alcoholic fatty liver disease in patients infected with H. pylori (crude odds ratio: 1.27, 95% CI: 1.17-1.33; and adjusted odds ratio: 1.22, 95% CI: 1.09-1.35). According to the subgroup analysis, the study region, sample size, and the method of diagnosing H. pylori were the factors contributing to the high heterogeneity. The meta-analysis revealed the increased risk of developing non-alcoholic fatty liver disease in patients infected with H. pylori. This indicates that H. pylori is a serious risk factor in patients susceptible to NAFLD.
