Perihilar cholangiocarcinoma arising in hepatitis C virus-related liver cirrhosis with hepatocellular carcinoma.
Article in Journal of gastroenterology, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Liver cirrhosis is reportedly one of the conditions preceding peripheral-type intrahepatic cholangiocarcinoma but not hilar/perihilar cholangiocarcinoma. Herein, we report a case of perihilar cholangiocarcinoma arising in a hepatitis C virus-related cirrhotic liver. The patient was a 69-year-old man. He was diagnosed with hepatitis C virus-related chronic hepatitis at the age of 56 years, and 9 years later, multiple hepatocellular carcinomas were detected by imaging modalities. Despite treatments, including chemotherapy, he died of hepatic failure at the age of 69 years. At autopsy, in addition to multiple nodules of hepatocellular carcinoma, we found a white mucinous and fibrous tumor spreading from the hepatic hilum to the periphery along the left lateral segmental bile ducts in the advanced cirrhotic liver. This tumor was histologically a cholangiocarcinoma that involved mainly the peribiliary glands and showed variable cystic dilation, suggesting that it might have been derived from these peribiliary glands. Immunohistochemically, the cholangiocarcinoma cells were positive for cytokeratin 7 and mucin core protein 1, and negative for cytokeratin 20 and mucin core protein 2. Hilar/perihilar cholangiocarcinoma arising in hepatitis C virus-related liver cirrhosis has rarely been reported. This case warrants further studies to clarify the possible involvement of hepatitis C virus in tumorigenesis of hilar/perihilar cholangiocarcinoma.
