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
backgroundMuscle-invasive urothelial carcinoma (MIUC) is a highly aggressive cancer associated with poor prognosis. Despite advancements in treatment, the optimal therapeutic approach remains unclear. Immune checkpoint inhibitors, when added to chemotherapy, have shown promise in improving patient outcomes.
aimsThis study aimed to evaluate the efficacy and safety of adjuvant tislelizumab combined with gemcitabine/cisplatin (Tisle+GC) compared to GC alone in patients with high-risk MIUC. MATERIALS &
methodsWe conducted a retrospective analysis of 117 patients with histologically confirmed pT3/4 and pN+ MIUC treated at our center between October 2016 and March 2023. Eligible patients received either Tisle+GC or GC alone, excluding those with prior neoadjuvant therapy. We compared disease-free survival (DFS), overall survival (OS), and treatment-related adverse events (AEs) between the two groups using Cox proportional hazards models and Kaplan-Meier estimates.
resultsThe Tisle+GC group showed significantly longer median DFS (19.08 vs. 9.06 months, HR = 0.114, p < 0.001) and OS (20.07 vs. 10.63 months, HR = 0.083, p = 0.026) compared to the GC group. Nerve tract invasion was identified as a significant predictor of poor outcomes (HR = 22.1, p = 0.003). Both groups experienced manageable grade 1-2 immune-related AEs, with pruritus being the most common, followed by liver function abnormalities and thyroid disturbances. Nonhematologic toxicities in the Tisle+GC group included elevated aspartate aminotransferase and hyponatremia, while the GC group mainly reported vomiting. No treatment-related fatalities occurred. DISCUSSION: The addition of tislelizumab to GC chemotherapy significantly improved both DFS and OS in high-risk MIUC patients. The safety profile was manageable, with immune-related AEs being predictable and not life-threatening. The findings support the potential of Tisle+GC as an effective adjuvant therapy.
conclusionTisle+GC is a promising adjuvant treatment for high-risk MIUC, offering improved survival outcomes with a manageable safety profile. Further prospective studies are needed to confirm these results and establish the long-term benefits of this combination therapy.
