Oncological outcome and survival predictors of widowed patients with bladder cancer in special populations.
Article in Scientific reports, 2025. 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
This study aimed to identify prognostic indicators and develop a nomogram to predict the overall survival (OS) of widowed bladder cancer (WBCa) patients. WBCa patients between 2004 and 2015 were identified using the Surveillance, Epidemiology, and End Results (SEER) database. The patients were randomly divided into the training and validation sets at a 7:3 ratio. Independent prognostic factors were determined using univariate and multivariate Cox analyses. We constructed a nomogram to predict 3- and 5-year for WBCa patients based on the results of multivariate Cox regression analysis. Consistency index (C-index), receiving operating characteristic (ROC), and calibration curve were used to assess the predictive accuracy of the nomogram. Gender, age at diagnosis, ethnicity, histologic type, histologic grade, tumor‑node metastasis (TNM) stage, and surgery were identified as independent predictors of OS. The C-index value of the nomogram for predicting OS was 0.704 and 0.701 in the training and validation cohorts, respectively. The ROC curves and calibration plots indicated that the model was relatively accurate. Independent prognostic factors for WBCa patients were identified, and a nomogram was constructed to predict the 3- and 5-year OS. The model enables clinicians to determine cancer patients' survival prognosis and formulate personalized treatment plans.
