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

introductionTissue sampling of gallbladder cancer (GBCa) is challenging because of the anatomy of the gallbladder. The aim of this study is to investigate the possibility of diagnosing GBCa patients by performing a liquid biopsy of bile in addition to current diagnostic methods.

methodsThirty patients with GBCa were enrolled in this study. Cytological examination was performed in all patients. Using next generation sequencing (NGS), DNA isolated from the bile and tumor tissue was analyzed for mutations in 49 oncogenes. We also compared these mutations with cytology results.

results57.1% of DNA samples from tumor tissue were positive for a mutation. In these patients, 87.5% of the bile circulating tumor DNA (ctDNA) samples had the same mutation. The concordance rate between bile ctDNA and tissue DNA samples was 85.7%, and the mutation frequencies detected in ctDNA were approximately half of what was detected in tumor tissue DNA. On the other hand, the sensitivity of the cytological and bile ctDNA analyses was 45.8% and 58.3%, respectively. The concordance rate between cytology and bile ctDNA analyses was 87.5%.

conclusionsMutated tumor DNA could be detected in bile by NGS. Liquid biopsy of bile might help us to diagnose GBCa because of higher sensitivity and positive predict value compared to cytology with ERCP.
