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
Background: Gallbladder cancer (GBC) represents a rare but aggressive malignancy, often diagnosed at an advanced stage. Although immune checkpoint inhibitors have improved outcomes in biliary tract cancers, GBC-specific evidence remains limited due to underrepresentation in pivotal clinical trials. Objectives: To evaluate the real-world effectiveness and safety of durvalumab combined with gemcitabine and cisplatin (Durva + gemcitabine and cisplatin (GemCis)) compared to GemCis alone in patients with advanced GBC. Design: Retrospective, multi-institutional cohort study. Methods: Data were collected from the TriNetX Global Collaborative Network. Adults diagnosed with advanced GBC between January 2020 and January 2025 who received Durva + GemCis or GemCis as first-line therapy were included. Propensity score matching (1:1) was performed based on age, sex, race, metastatic sites, and tumor marker levels. The primary outcome was overall survival (OS), whereas secondary outcomes included adverse events (AEs). Results: Among 2458 patients with advanced GBC, 130 received Durva + GemCis and 201 received GemCis. After matching, 111 patients per group were analyzed. Median OS was significantly longer in the Durva + GemCis group compared to the GemCis group (13.1 vs 8.5 months; log-rank Conclusion: In this real-world study, the addition of durvalumab to GemCis was associated with improved OS in patients with advanced GBC, with a manageable safety profile. These exploratory findings should be interpreted with caution, underscoring the need for dedicated GBC-specific prospective trials.
