Predicting early death in elderly patients with bladder urothelial carcinoma: a population-based study.

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: The incidence and mortality rates of bladder urothelial carcinoma significantly increase with age after the age of 60 years. In our study, we aimed to identify and analyze the risk factors for early death (death within 6 months) in elderly patients with bladder urothelial carcinoma and established a reliable Nomogram model, thereby assisting clinicians to choose the best clinical decision-making. Methods: Data of elderly patients with bladder urothelial carcinoma from the Surveillance, Epidemiology, and End Results (SEER) database (version 8.4.4) between 2010 and 2015 were selected. Multivariate logistic regression analysis was used to identify independent risk factors associated with early death. A predictive Nomogram was constructed based on these risk factors to assess the risk of early death. During the training and validation processes, the clinical applicability and predictability of the model was evaluated using receiver operating characteristic (ROC) curves, calibration analysis and decision curve analysis (DCA). Results: In this study, a total of 5,087 patients with bladder urothelial carcinoma were collected, among whom 1,163 experienced early death. Age, marital status, tumor (T)-stage, metastasis (M)-stage, surgery, radiation, chemotherapy, brain metastasis, and tumor size were all identified as independent risk factors for early death. Based on these factors, we constructed a nomogram that can effectively predict early death in elderly patients with bladder urothelial carcinoma. The nomogram shows that the areas under the curve (AUCs) were 0.7938 and 0.8107 for the training and validation cohorts respectively, and the DCA showed that the predictive model performed well and could be applied in the clinic. Limitations of this study: potential selection bias, lack of relevant variables such as comorbidities, family history, and lack of external validation. Conclusions: In this study, we constructed and validated a predictive model (Nomogram) to accurately predict the clinical prognosis of elderly patients with bladder urothelial carcinoma. This predictive tool provides clinicians with an individualized prognostic assessment that can optimize the development of treatment regimens and improve patients' clinical outcomes and quality of survival.
