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 and Aim: Non-alcoholic fatty liver disease (NAFLD) is a common health problem related to diet and a sedentary lifestyle. Zinc has essential roles in diabetes, insulin resistance and inflammation. This meta-analysis aims to evaluate the relationship between NAFLD and dietary zinc intake/serum zinc levels. Materials and Methods: A systematic search was performed in PubMed, Web of Science, and Scopus databases for relevant English articles with mean/standard deviation values of serum zinc levels (µg/dL) and dietary zinc intake (mg/day) up to February 2020. We screened "fatty liver disease" and "zinc" keywords; totally 864 articles, eight of them were found to have suitable serum zinc level or daily zinc intake data for meta-analysis. Results: Serum zinc level in NAFLD patients were lower than healthy controls (data from 984 individuals, FEM, p<0.00001). The meta-analysis results of the nutritional zinc intake of totally 19438 individuals were similar in NAFLD and control groups (FEM, p=0.36). Conclusion: Serum zinc levels were lower in NAFLD patients, even though they have similar zinc intake in the diet, which suggests that there may be an absorption problem or increased need, with a distributional disorder which results in lower serum zinc levels. Further studies need to evaluate the role of zinc in NAFLD.
