Imaging Features and Clinical Outcomes of Ischemic Cholangiopathy After Drug-Eluting Bead Transarterial Chemoembolization for Hepatocellular Carcinoma: A Retrospective Single-Center Cohort Study and Literature Review.
Review in Current oncology (Toronto, Ont.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIschemic cholangiopathy (IC) is an under-recognized complication after transarterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). Our goal was to estimate the incidence, timing, clinical presentation, and management of IC after drug-eluting bead TACE.
methodsSingle-center retrospective cohort of consecutive drug-eluting bead TACE procedures (1 January 2020-31 December 2023) with imaging follow-up to 31 December 2024 was conducted. IC was defined radiologically as bile duct dilatation without mechanical obstruction, biloma formation, biliary strictures, or ischemic cholecystitis occurring after TACE. The primary outcome was the incidence of IC. Secondary outcomes included clinical presentation, need for hospitalization, and management.
resultsAmong 106 patients, 14 developed IC (13.2%). Imaging abnormalities were detected a mean of 3.1 months after TACE. Six patients (42.9%) were asymptomatic. Among symptomatic patients, the most common manifestations were abdominal pain (
conclusionsIC after TACE is not rare and is frequently asymptomatic, often detected incidentally on routine CT follow-up. Systematic biochemical monitoring and selective MRCP could improve detection, particularly when TACE sessions are closely spaced.
