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
Peribiliary glands are complex lobular structures containing mucus and serous glands, distributed along the extrahepatic and intrahepatic bile ducts. In this report, we describe a case of intraductal papillary neoplasm of the bile duct suspected to be of peribiliary glands origin. The patient was an 80-year-old man who was referred to our hospital for a hepatic mass. On further examination, a 38 × 34 mm cystic lesion with papillary growth was found in S1/4. Because the lesion was extensively bordered by both hepatic ducts and the connection was unclear, it was difficult to determine the extent of hepatic resection. To confirm the location, a peroral cholangioscopy was performed. The connection with the cyst was detected in the right hepatic duct and a villous tumor mucosa protruded through the conduit lumen. Since we found that the lesion communicated with the right hepatic duct, a right hepatectomy was subsequently performed. The postoperative pathological diagnosis was an intraductal papillary neoplasm of the blie duct with associated invasive carcinoma. The postoperative course was good, and the patient experienced no recurrence.
