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: Lymph node metastasis represents a critical prognostic factor in bladder cancer and significantly influences treatment choice and outcomes. Objective: To evaluate the predictive value of the maximum short-axis diameter of pelvic lymph nodes on preoperative computed tomography-urography (CTU), in combination with inflammatory markers, in the prediction of lymph node metastasis in radical cystectomy (RC) patients. Methods: A retrospective analysis was conducted on 210 patients who had received CTU within one month before RC at Beijing Friendship Hospital from January 2016 to December 2023. Upon screening, 174 patients were included and assigned into two groups based on postoperative pathology: i.e., lymph node metastasis group (n = 43) and non-metastasis group (n = 131). The neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR) were calculated. The maximum short-axis diameter of a lymph node ≥8 mm was considered indicative of metastasis. Receiver operating characteristic (ROC) curve analysis was performed to assess predictive performance, determine optimal cutoffs, and construct a prediction model using multivariate logistic regression. Results: Significant differences ( Conclusion: A nomogram incorporating CTU findings, clinical T stage, MLR, and PLR effectively predicts lymph node metastasis in RC patients. However, further multi-center validation is required before clinical implementation.
