Whole-genome sequencing of 20 cholangiocarcinoma cases reveals unique profiles in patients with cirrhosis and primary sclerosing cholangitis.

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: Cholangiocarcinoma (CCA) is a molecularly heterogenous disease that is often fatal. Whole genome sequencing (WGS) can provide additional knowledge of mutational spectra compared with panel sequencing. We describe the molecular landscape of CCA using whole-genome sequencing and compare the mutational landscape between short-term and long-term survivors. Methods: We explored molecular differences between short-term and long-term survivors by performing WGS on 20 patient samples from our biliary tract cancer database. Short-term survivors were enriched for cases with underlying primary sclerosing cholangitis (PSC) and patients with cirrhosis. All samples underwent tumour epithelial enrichment using laser capture microdissection (LCM). Results: Dominant single base substitution (SBS) signatures across the cohort included SBS1 and SBS5, with the latter more prevalent in long-term survivors. SBS17 was evident in 3 cases, all of whom had underlying ulcerative colitis (UC) with PSC. Additional rare signatures included SBS3 in a patient treated for prior mantle cell lymphoma and SBS26/SBS6 in a patient with a tumor mutational burden of 33 mutations/Mb and a pathogenic Conclusions:
