Hilar cholangiocarcinoma with extensive immunoglobulin G4 reaction.

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
Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is a systemic fibroinflammatory disorder that can involve multiple organs. It is often challenging to distinguish IgG4-related sclerosing cholangitis (IgG4-SC) from cholangiocarcinoma because of overlap in their clinical findings. A 75-year-old man presented to a hospital for a detailed examination of the elevation of some biliary enzymes. Radiographic examination revealed segmental bile duct with wall thickening of the common hepatic bile duct, and dilation of the peripheral branches. Transampullary biopsy showed a non-specific inflammatory reaction with several IgG4-positive cell infiltrations. There were no signs of malignancy. The liver biopsy showed bile duct injury accompanied by IgG4-positive cell infiltration. We then performed bile duct biopsy and finally diagnosed the patient with cholangiocarcinoma. We should remember that the IgG4 reaction is neither completely sensitive nor specific for IgG4-RD and avoid resting solely on the IgG4 reaction to precisely distinguish IgG4-SC from cholangiocarcinoma.
