Abnormal lipid profiles are associated with markers of impaired fibrinolysis in patients with cirrhosis.

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.
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: Patients with liver cirrhosis exhibit abnormalities in lipid metabolism and in circulating proteins of clot breakdown. Recent studies have shown relationships between dyslipidemia and fibrinolytic abnormalities in noncirrhotic populations. Objectives: We investigated associations between lipid profiles and fibrinolytic markers in patients with cirrhosis. Methods: This observational study analyzed samples from 147 patients with stable cirrhosis, decompensated cirrhosis, acute-on-chronic liver failure, and sepsis without pre-existing chronic liver disease, and from 38 healthy controls. We studied fibrinolysis by clot lysis time (CLT), plasminogen, plasminogen activator inhibitor-1 (PAI-1), and tissue-type plasminogen activator (tPA), and lipid profiles by apolipoproteins A1 and B, common lipoproteins, triglycerides, and total cholesterol. Results: CLT was slightly enhanced in stable and decompensated cirrhosis, but prolonged in acute-on-chronic liver failure and sepsis. Plasminogen levels decreased, whereas PAI-1 and tPA increased with cirrhosis severity. All lipid parameters decreased with cirrhosis severity, besides triglyceride levels, which were preserved. In an analysis of all patients with cirrhosis combined, apolipoprotein A1 correlated inversely with CLT, levels of PAI-1 and tPA, and positively with plasminogen. Apolipoprotein B, low-density lipoprotein, and lipoprotein(a) correlated positively with plasminogen. Triglycerides correlated positively with CLT. Conclusion: Cirrhosis is characterized by decreased (apo)lipoprotein levels, preserved triglyceride levels, and a shift from enhanced to impaired fibrinolysis with increasing disease severity. Lower apolipoprotein A1 levels and higher triglyceride levels are associated with impaired fibrinolysis, which may reflect biological interactions between lipid metabolism and fibrinolysis or parallel alterations secondary to hepatic dysfunction.
