Determination of Nitrogen Metabolism-Related Prognostic Signatures for Forecasting Bladder Cancer Prognosis
Article in Endocrine, metabolic & immune disorders drug targets, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundBladder cancer is one of the major health threats worldwide, and aberrant regulation of nitrogen metabolism is closely related to its development. Understanding the role of nitrogen metabolism-related genes in BC is pivotal for the development of new therapeutic strategies and prognostic assessment. AIM AND
objectivesThis study aimed to explore the prognostic factors associated with nitrogen metabolism in bladder cancer (BC) and to construct a prognostic model.
methodsDifferential expression gene analysis was performed to identify genes associated with nitrogen metabolism by analyzing mRNA expression data from BC patients. The prognostic relationship between these genes and BC patients was analyzed using univariate Cox regression. One hundred one combinatorial machine learning methods were applied for feature selection, and key prognostic genes were identified based on the method with the highest combined score. Immunocyte infiltration analysis was carried out to assess the tumor microenvironmental characteristics of patients in different risk groups.
resultsTwenty-five genes significantly associated with prognosis were identified from nitrogen metabolism-related genes. Twenty-three most prognostically predictive signature genes were screened under feature screening with multiple machine-learning models. Immune cell infiltration analysis showed that patients in the high-risk group had significantly different immune cell infiltration, suggesting that these genes may influence BC progression by regulating immune escape mechanisms. These results provide new biomarkers and potential therapeutic targets for precision treatment and prognostic assessment of BC.
conclusionThe expression patterns of nitrogen metabolism-related genes identified can be used as effective biomarkers for bladder cancer prognosis, providing a scientific basis for personalized treatment. Future studies can further explore the specific biological functions and mechanisms of action of these genes to promote more effective clinical applications.
