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 aims: Hepatic infarcts are uncommon vascular lesions due to dual vascular supply of the liver characterized by the peripherally-located wedge-shaped large zones of necrosis in the hepatic parenchyma. They are commonly seen as a complication of liver transplant. Material and methods: The cases of hepatic infarcts of the native liver detected in medical autopsies were searched in the archives and their clinical, biochemical, gross, and histomorphological details were retrieved. Results: Three cases of hepatic infarct of the native liver were detected from among 1865 consecutive cases of adult and pediatric autopsies (0.2%). These cases were caused by hornet stings, acute pancreatitis, and hemolysis, elevated liver enzymes, low platelet syndrome (HELLP) in a 24-year-old male, 19-year-old male, and a 28-year-old postpartum female, respectively. The first two cases showed 50-150 times elevated transaminases and conjugated hyperbilirubinemia. All cases showed hyperemic to pale subcapsular infarcts. The HELLP syndrome case showed intrasinusoidal fibrin-rich microthrombi, while the other two cases showed the presence of fibrin-rich/organized microthrombi involving variable-sized portal and central venous radicles. Two of these cases (hornet sting and HELLP syndrome) did not show any macroscopic thrombi in the portal vein, hepatic artery, or hepatic veins. Conclusion: Hepatic infarcts are rare vascular lesions found in the nontransplant liver. The gross and histomorphology of these lesions depend on the age of these lesions. They can occur in the presence of vascular microthrombi in the absence of any documented macroscopic thrombus.
