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

backgroundGBC is an aggressive biliary tract malignancy with limited survival. Although actionable genomic alterations (AGAs) are increasingly recognized in GBC, their prognostic association in real-world practice remains incompletely defined because genomic status is often confounded by stage at presentation and treatment selection. We evaluated the association between documented AGA status and overall survival (OS) using a tiered matching strategy to account for major clinical confounders.

methodsUsing the TriNetX Global Collaborative Network, we identified adults with GBC and stratified them into patients with at least one documented AGA in

resultsA marked disparity in genomic documentation was observed before matching, with unknown race recorded in 51.0% of the comparison cohort versus 3.7% of the documented AGA cohort. In the demographic-matched analysis (Model 1), the documented AGA cohort had higher mortality (52.8% vs. 42.5%,

conclusionsIn this real-world matched analysis, the presence of documented AGAs in GBC were associated with higher mortality even after matching for major demographic, stage-related, and treatment-related variables. These findings support the prognostic relevance of genomic status in GBC and underscore the need to address disparities in access to genomic documentation and testing.
