Comparing the efficacy and complications of Endoscopic Biliary Drainage (EBD) and Percutaneous Transhepatic Biliary Drainage (PTBD) in patients with perihilar cholangiocarcinoma.
Article in Journal of family medicine and primary care, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Introduction and Objective: Hilar cholangiocarcinoma (HCCA) is a rare malignancy in patients with biliary disease. If jaundice and obstruction before surgery are left untreated, then they can cause side effects such as cholangitis, delayed tumor treatment, decreased quality of life, and increased mortality. Surgery is the main treatment for HCCA. Therefore, this study was performed to compare the efficacy and complications of percutaneous transhepatic biliary drainage (PTBD) and endoscopic biliary drainage (EBD). Methods: This cohort study was conducted on 20 patients with biliary obstruction who had been selected by simple random sampling and divided into two groups of EBD and PTBD. Three weeks after surgery, patients were compared in terms of bilirubin levels and postoperative complications. Data were analyzed by descriptive statistics (table, mean, and standard deviation) and inferential statistics (independent t-test, Chi-square test, and Fisher's test). Results: Independent Conclusion: Using both drainage methods before surgery reduced bilirubin levels in patients, but EBD method had fewer side effects than PTBD method. The EBD method was performed under the direct supervision of a gastroenterologist. In performing this procedure, specialist physicians should have more supervision.
