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

A 78-year-old man had received interferon therapy and achieved sustained virologic response for chronic hepatitis C 10 years before. He came to our hospital due to liver damage. Abdominal ultrasonography showed a 90-mm mass lesion in the liver. The echoic level was high in the central part and low in the edge of the tumor. Moreover, there was an accumulation of low echoic irregular mass lesions around the hepatic portal region. Cervical ultrasonography also revealed several 15-mm mass lesions on the left clavicle, the imaging character of which was similar to the liver tumor. The liver tumor seemed to be hypovascular on dynamic computed tomography, but contrast-enhanced ultrasonography showed hyperenhancement at the early vascular phase and at maximum intensity projection showed a treelike branch vascular structure that derived from the central part to the margin of the mass. A needle biopsy of the liver tumor and a cervical lymph node resection were performed, which led to the definitive diagnosis of undifferentiated carcinoma of the liver with multiple lymph node metastasis, upon histological analysis. Undifferentiated carcinoma of the liver is extremely rare and contrast-enhanced ultrasonography was the most useful device for evaluating vascular characteristics in this case.
