The Impact of Chronic Kidney Disease on Postoperative Outcomes in Patients With Bladder Cancer: A Meta-Analysis.

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: Bladder cancer (BC) is a common malignancy, and chronic kidney disease (CKD) is an increasingly prevalent comorbidity that may adversely affect oncological outcomes. However, the prognostic impact of CKD in patients with BC remains unclear. We investigated the association between CKD and postoperative outcomes in patients with BC. Methods: This study was registered in PROSPERO (CRD420261417895). A systematic search of PubMed, Web of Science, Embase, and Cochrane Library was conducted from database inception up to June 8, 2026. The investigation concentrated on two primary keywords: BC and CKD. Stata SE 18 and R 4.5 were used for data analysis. Results: Seven studies involving 2756 patients were included in this meta-analysis. CKD was significantly associated with increased risks of progression (OR = 2.23, 95% CI: 1.34-3.73, P < 0.05), recurrence (OR = 1.82, 95% CI: 1.53-2.18, P < 0.05), and poorer cancer-specific survival (CSS) (OR = 3.39, 95% CI: 1.45-7.94, P < 0.05). Conversely, no significant association was observed between CKD and overall survival (OR = 1.32, 95% CI: 0.65-2.69, P = 0.45). Conclusions: CKD correlated with unfavorable postoperative outcomes in patients with BC, particularly progression, recurrence, and CSS. These findings suggest that CKD may represent a clinically relevant prognostic factor that could aid risk stratification and postoperative surveillance. Further prospective studies are warranted to validate these findings.
