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
Background: This study aims to analyze the risk factors for preoperative pyuria in patients with ureteral calculi (UC). On the basis of clarifying the presence of pyuria, it focuses on exploring the risk factors for concurrent pathogenic pyuria, and meanwhile constructs a simple and practical prediction model to assess the risk of its occurrence, so as to provide a reference basis for clinical early preoperative intervention in such patients. Methods: From January 2019 to May 2025, a total of 1182 patients with UC were enrolled in this study. First, they were divided into a pyuria group and a nonpyuria group. Logistic regression analyses were used to screen out the risk factors associated with pyuria. To enhance the reliability and robustness of the results, a sensitivity analysis was further performed to verify the conclusions. Subsequently, the pyuria group was further divided into 2 subgroups, namely a pathogenic pyuria group and a sterile pyuria group. Using the same methods mentioned above, the relevant risk factors for preoperative concurrent pathogenic pyuria in patients with UC were identified, and a corresponding prediction model was constructed, which was then validated using receiver operating characteristic (ROC) curves and calibration curves. Results: A total of 1182 patients with UC were enrolled in this study, including 250 cases (21.15%) receiving nonsurgical treatment and 932 cases (78.85%) undergoing surgical treatment. Among them, 630 cases (53.30%) were diagnosed with pyuria. Multivariate logistic regression analysis combined with sensitivity analysis showed that female gender ( Conclusions: This study not only confirms that female gender, bilateral UC, stone size, and hydronephrosis size are independent risk factors for preoperative pyuria in patients with UC, but also further identifies that female gender, comorbid diabetes mellitus, and hydronephrosis size > 40 mm are independent risk factors for preoperative concurrent pathogenic pyuria in such patients. The prediction model constructed accordingly can effectively assess the risk of preoperative concurrent pathogenic pyuria in female patients with UC, providing a practical reference basis for clinicians to implement early preoperative intervention in such patients.
