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
backgroundUrothelial carcinoma (UC) is a common malignancy with a poor prognosis in advanced stages, characterized by high heterogeneity, recurrence risk, and chemotherapy resistance. There is a clinical lack of reliable prognostic markers. Human epidermal growth factor receptor 2 (HER2) is a key oncogene and therapeutic target. Its correlation with clinicopathological features in Chinese UC patients remains controversial, leading to unclear biomarker value and limiting the precise application of therapies like RC48-ADC. Therefore, clarifying the association between HER2 expression and UC pathological staging and prognosis is crucial for optimizing treatment.
methodsClinical data of 444 UC patients admitted to Fujian Provincial Hospital from January 2020 to August 2024 were retrospectively analyzed. HER2 expression was detected by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). Spearman's rank correlation coefficient was used to clarify the association between HER2 and clinicopathological characteristics, and Kaplan-Meier method and Cox regression model were applied to analyze its prognostic value.
resultsThe high HER2 expression rate (IHC 2+/3+) was 40.05%. High HER2 expression was significantly correlated with Age, History, Routine Urine Test indices, Pathological Grade, Ki67 index, p53 expression, and treatment options (all P<0.05). Multivariate Cox regression analysis confirmed that high HER2 expression was an independent risk factor for UC Recurrence (HR=2.496, P=0.044) but not significantly associated with Metastasis (P=0.923).
conclusionHER2 is highly expressed in UC patients in the Fujian region, correlating with aggressive clinicopathological features. It can serve as a reliable biomarker for predicting recurrence risk, guiding postoperative management and targeted therapy selection.
