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
Objective: To explore the diagnostic performance of blood urea nitrogen-to-creatinine (BUN/Cr) ratio in differentiating the site of gastrointestinal bleeding, and to assess the predictive value of early elevated BUN/Cr ratio for clinical outcomes in patients with acute nonvariceal upper gastrointestinal bleeding (ANVUGIB). Methods: The adult patients diagnosed with gastrointestinal bleeding who were hospitalized in the Department of Gastroenterology, Zhongshan Hospital, Xiamen University between May 2020 and May 2021 were retrospectively enrolled. According to the site of gastrointestinal bleeding, the patients were divided into the upper gastrointestinal tract group, the proximal small intestinal bleeding group, and the distal small intestinal and colonic bleeding group. According to the early dynamic changes of BUN/Cr ratio within 6-48 hours after admission, patients with ANVUGIB were divided into early dynamic elevated BUN/Cr ratio group and non-early dynamic elevated BUN/Cr ratio group. Receiver operating characteristic (ROC) curve was used to analyze the diagnostic performance of BUN/Cr ratio in differentiating the site of gastrointestinal bleeding and examine the predictive efficacy of early dynamic elevated BUN/Cr ratio after admission, Rockall scoring system, and the combined indicator of the two for estimating the primary clinical outcomes in ANVUGIB patients. Results: A total of 266 patients were enrolled. Among them, 204 cases were in the upper gastrointestinal bleeding group, 15 cases were in the proximal small intestinal bleeding group, and 47 cases were in the distal small intestinal and colonic bleeding group. In the ANVUGIB patients, 16 were in the group with early dynamic elevated BUN/Cr ratio after admission, and 146 were in the group with non-early dynamic elevated BUN/Cr ratio after admission. The area under the ROC curve of the BUN/Cr ratio was 0.831 (95% Conclusion: The BUN/Cr ratio shows rather reliable diagnostic performance for identifying the site of gastrointestinal bleeding, and the early dynamic elevated BUN/Cr ratio after admission is a reliable indicator for predicting clinical outcomes in patients with ANVUGIB.
