1 · What the graph read from it

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.

2 · The registry

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

backgroundIntrahepatic cholangiocarcinoma (iCCA) is a rare liver malignancy with poor prognosis. This study assessed how case discussion of patients at expert centers within multidisciplinary team meetings (MDTs) is associated with treatment and survival in iCCA patients in the Netherlands.

methodsThis retrospective cohort study analyzed data registered in the Netherlands Cancer Registry between 2017 and 2021 on all consecutive patients diagnosed with iCCA. Data included patient demographics, tumor characteristics, and the involvement of a member of an expert center at case discussions. Outcomes included overall survival and treatment type, which was specified as tumor-directed (e.g., resection, ablation, systemic treatment, or other treatment modalities) vs. supportive care only.

resultsAmong the 1.622 patients included, median overall survival was 5.4 months, and 825 (50.9%) underwent tumor-directed therapy. Patients discussed at expert centers (59.6%) were more likely to receive tumor-directed therapy (58.8% vs. 37.2%, P < 0.001) and undergo surgery (20.3% vs. 5.7%, P < 0.001). In the multivariable analysis, patients discussed at expert centers had better overall survival (hazard ratio 0.69 (0.62-0.78)).

conclusionsCentralized care through MDT discussion at expert centers was associated with increased likelihood of receiving tumor-directed therapy and improved survival in iCCA patients. This study highlights the potential for improved patient outcomes through structured expert consultations.
