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
There is no specific method for the preoperative diagnosis of atypical bile duct hyperplasia, which is a precursor of cholangiocarcinoma. This study aimed to create a new model for diagnosing atypical bile duct hyperplasia based on routine laboratory tests in patients with intrahepatic lithiasis.The new diagnostic model was developed with a derivation cohort that included 375 patients with intrahepatic lithiasis. Clinical and pathological data were retrospectively collected. Prognostic factors were evaluated with univariate and logistic regression analyses. The validation cohort included 136 patients who were retrospectively screened to quantify the model's predictive value.Age and Carbohydrate Antigen 19-9 (CA-199) were revealed to be diagnostic indicators of atypical bile duct hyperplasia in patients with intrahepatic lithiasis. The new diagnostic model was created with the formula: -6.612 + (0.002 × CA-199) + (0.072 × Age). The area under the receiver operating curve of the model was 0.721. With 0.25 as the cutoff point, the sensitivity and specificity of this model in the derivation cohort were 13.9% and 95.9%, respectively. In the validation cohort, these values were 28.5% and 88.7%, respectively. The novel model has an acceptable and stable ability to predict atypical hyperplasia in the intrahepatic bile duct.This novel model provides a simple system for diagnosing atypical bile duct hyperplasia before surgery in patients with intrahepatic lithiasis.
