Recent 5‑year trends in biliary tract cancer survival rates: An analytical big data survey.
Article in Medicine international. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Biliary tract cancer (BTC), also known as cholangiocarcinoma, is a relatively rare type of cancer with a poor prognosis. Despite the combination of chemotherapy and advances in targeted therapy, which have potentially improved the prognosis of patients with BTC, research on outcomes remains inadequate. The present study thus analyzed the survival trends of patients with BTC. The present study used anonymized data from a public national database and focused on 13,600 individuals diagnosed with BTC between 2015 and 2020. The overall and 1-year mortality rates were analyzed according to cancer anatomic sites, along with the impact of comorbidities, such as diabetes and hepatitis on these rates. A total of 13,600 patients were included in the analysis; 26.31% of the patients had intrahepatic BTC, 27.46% had extrahepatic BTC and 46.24% had gallbladder (GB) cancer. For all BTC types, the 1-year survival hazard ratio (HR) in 2018 was 0.992 compared with that in 2015, and 0.986 in 2019. Compared with intrahepatic BTC, the 1-year survival rate was 0.349 for GB cancer and 0.641 for extrahepatic BTC. Patients with diabetes had an HR of 1.318 compared with those without diabetes. For patients with BTC previously diagnosed with GB stones, the survival HR was 0.902, compared to those without GB stones. On the whole, the analysis of national healthcare big data indicated an improvement in the overall prognosis of patients with BTC from 2018. Moreover, these data highlight that the prognosis of patients with BTC is influenced by the anatomical location of the cancer, and that co-existing medical conditions in patients affect the survival rate.
