Prognostic values of distal ureter involvement and survival outcomes in bladder cancer at T1 and T2 stages: a propensity score matching study.
Article in International urology and nephrology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo study prognostic values of distal ureter involvement (DUI) and survival outcomes in bladder cancer at T1 and T2 stages.
methodsThe national Surveillance, Epidemiology, and End Results database (2004-2015) was applied to obtain bladder cancer patients. We used the Kaplan-Meier method with the log-rank test, subgroup analyses, the multivariable Cox proportional hazard model and propensity score matching (PSM).
resultsA total of 490 patients with DUI and 28,498 patients with non-DUI (non-involvement) were enrolled in our study. After 1:1 PSM, 490 matched pairs were picked out. The multivariable Cox regression before and after PSM revealed that the DUI group had a high risk of overall mortality (HR = 1.374, P < 0.001 before PSM; HR = 1.513, P < 0.001 after PSM) and cancer-specific mortality (HR = 1.632, P < 0.001 before PSM; HR = 1.699, P < 0.001 after PSM). The results of survival analyses showed that patients in the DUI group had lower survival probability in OS (P = 0.0011) and CSS (P < 0.0001) analyses. Nevertheless, in the subgroup analysis, significant differences were only observed in the T1 stage in terms of CSS and T2a stage in terms of OS and CSS (all P < 0.05).
conclusionThe prognosis of DUI was poorer than that of non-DUI. DUI was an independent risk factor for OM and CSM in bladder cancer at T1 and T2 stages especially for those at T1 and T2a stages.
