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

The association between alcohol and liver disease, including alcoholic hepatitis, cirrhosis, acute-on-chronic liver failure, and hepatocellular carcinoma, has been well described, but the same cannot be said for the association between smoking, water pipe or tobacco chewing. A review of cumulative evidence suggests that smoking is independently a risk factor for liver fibrosis and contributes to carcinogenesis in HCC. Smoking-related fibrosis has been reported in patients with nonalcoholic fatty liver disease, primary biliary cholangitis, alcoholic liver disease and chronic viral hepatitis. Heavy smoking leads to systemic inflammation, oxidative stress, insulin resistance, and results in tissue hypoxia, as well as free radical damage. Other than damaging the liver, patients also suffer from the systemic effects of the 4000 chemicals associated with tobacco, which include nitrosamines, aromatic hydrocarbons, nicotine, nornicotine, and other alkaloids. These include respiratory ailments, cancer of the lungs, oral cavity, esophagus, pancreas and colon, atherosclerotic vascular disease, and stroke.
