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 &

aimsAlthough primarily a disease with liver-specific complications, nonalcoholic fatty liver disease (NAFLD) is a systemic disease with extrahepatic complications. We aim to evaluate the association between NAFLD and cardiovascular disease (CVD), stroke and cerebrovascular disease, and extrahepatic cancers.

methodsWe searched MEDLINE, EMBASE, and Cochrane Systematic Review Database from January 1, 2000 to July 1, 2019 to identify peer-reviewed English language literature using predefined keywords for NAFLD, CVD, stroke and cerebrovascular disease, and extrahepatic cancers among adults. Two reviewers independently selected studies for inclusion. Measures of association between NAFLD and CVD, stroke and cerebrovascular disease, and extrahepatic cancers were extracted. Quality assessed using Newcastle-Ottawa scale and Grading of Recommendations Assessment, Development and Evaluation (GRADE).

resultsThirty studies were included evaluating CVD, 16 studies evaluating stroke or cerebrovascular disease, and 13 studies evaluating extrahepatic cancers. On pooled meta-analysis assessment, NAFLD was associated with increased risk of CVD (risk ratio [RR]: 1.78; 95% confidence interval [CI]: 1.52-2.08) and stroke or cerebrovascular disease (RR: 2.08, 95% CI: 1.72-2.51). Significant heterogeneity in assessing extrahepatic cancers prevented applying meta-analysis methods, but NAFLD seemed to be associated with increased risk of breast and colorectal cancers. Overall level of quality of studies were very low by GRADE.

conclusionsNAFLD is associated with increased risks of CVD and stroke or cerebrovascular disease among adults. There appears to be increased risk of breast and colorectal cancers. Given low quality of evidence, it is premature to make any strong conclusions to modify CVD, stroke, or cancer screening policies in patients with NAFLD.
