Combined hepatocellular cholangiocarcinoma: A rare hepatic malignancy exhibiting concurrent imaging features of hepatocellular carcinoma and intrahepatic cholangiocarcinoma.

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
Combined hepatocellular cholangiocarcinoma (cHCC-CC) is a rare primary hepatic neoplasm characterized by the coexistence of hepatocellular and cholangiocellular differentiation within the same tumor. The diagnosis is challenging because imaging characteristics may resemble those of hepatocellular carcinoma (HCC) or intrahepatic cholangiocarcinoma (ICC), depending on the dominant histologic component. We present a case of cHCC-CC demonstrating discrete regions with imaging features of both HCC and ICC, along with elevation of both alpha-fetoprotein and carbohydrate antigen 19-9. Recognition of discrete imaging features of HCC and ICC in the same mass should raise suspicion for cHCC-CC when evaluating primary liver neoplasms. Accurate diagnosis of cHCC-CC is important for prognostication and to guide clinical decision-making.
