Sarcomatous carcinoma in biliary system: A retrospective study.
Observational study in Medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Sarcomatous carcinoma in biliary system, including sarcomatous intrahepatic cholangiocarcinoma (SIC) and sarcomatous choledochal carcinoma (SCC), is extremely rare and malignant.This retrospective study included 5 patients with SIC and 4 patients with SCC. Their basic characteristics, preoperative lab tests, preoperative imaging features, perioperative status, and follow-up information have been collected and analyzed.Lesions at different locations induced various preoperative symptoms. The history of choledocholithiasis or hepatolithiasis was remarkable in patients with SIC. Cancer antigen 19-9 appeared to be a key factor for both SIC and SCC. However, preoperative lab tests or imaging features could not distinguish SIC from intrahepatic cholangiocarcinoma, or SCC from choledochal carcinoma. Surgical treatments for all 9 patients were successful. Efficacy of adjuvant chemotherapy was not ideal. The prognosis of sarcomatous biliary carcinoma was enormously poor.Sarcomatous carcinoma in biliary system is extremely rare and malignant. Chronic inflammation could be critical in the currently unknown occurrence mechanism. Further research is urgently needed to improve the prognosis.
