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
introductionLeft trisectionectomy with bile duct resection is a high-risk procedure that requires thorough preoperative evaluation to prevent postoperative liver failure. In addition, there are a few reports of highly invasive hepatectomy in cases where hepatic vein thrombosis is present preoperatively. CASE PRESENTATION: In a 58-year-old man, papillary epithelium was detected in the left hepatic duct during a bile duct biopsy, and the anterior segment of Glisson's capsule was compressed by the cystic components. Left trisectionectomy with bile duct resection was planned, based on a diagnosis of intraductal papillary neoplasm of the bile duct (IPNB). In our department, portal vein embolization (PVE) is essential when considering left trisectionectomy with bile duct resection, so surgery was scheduled after PVE. However, CT after PVE showed thrombus formation in the right hepatic vein (RHV), which persisted despite the initiation of anticoagulant therapy. Owing to the absence of a major drainage vein and the risk of postoperative liver failure, the patient was treated with gemcitabine + cisplatin + S-1 therapy. CT after chemotherapy still showed RHV thrombosis, along with newly developed peripheral venous shunt formation between the obliterated RHV branches. After 6 months, the same findings were observed, and as the tumor had shrunk, the case was deemed resectable. Left trisectionectomy with bile duct resection was performed. Pathological diagnosis confirmed IPNB (pTisN0M0, pStage 0 according to the Union for International Cancer Control, 8th edition). Following adjuvant chemotherapy, the patient developed pulmonary metastases, which were surgically resected. As of 38 months post-hepatectomy, the patient remains cancer-free.
conclusionsWe encountered a case in which left trisectionectomy with bile duct resection was possible owing to the formation of an RHV shunt, enabling resection of both the primary and recurrent lesions. Continuous imaging is essential for the dynamic assessment of resectability.
