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: Some urothelial carcinoma patients are ineligible for platinum-based chemotherapy, necessitating exploration of other effective therapeutic strategies. Human epidermal growth factor receptor 2 (HER2) protein overexpression, gene amplification or mutations exist in urothelial carcinoma. Our study is to investigate the correlation of three-tier assessment of HER2 expression with clinical pathological characteristics and prognosis of urothelial carcinoma. Methods: HER2 expression in 75 urothelial carcinomas from Jiangsu Cancer Hospital was re-scored by immunohistochemistry and fluorescence in situ hybridization according to HER2 three-tier assessment standards. Its relationship with various pathological parameters of urothelial carcinoma and its correlation with prognosis were analyzed. And validate in The Cancer Genome Atlas (TCGA) cohort. Results: HER2 expression was observed in 82.7% (62/75) of urothelial carcinoma patients, of which HER2-low expression accounted for 61.3% (46/75). HER2 expression was significantly correlated with the tumor-nodes-metastasis (TNM) stage of urothelial carcinoma (P=0.043) and HER2-low was an independent poor prognostic factor for patients with urothelial carcinoma (P=0.04). Follow-up showed that HER2-low patients had the worst prognosis compared with HER2-negative (P=0.02) and HER2 positive (P=0.02) and also had the highest progression rate in TCGA cohort (P=0.02); receiver operator characteristic (ROC) model suggested HER2-low could effectively predict prognosis. Conclusions: HER2 expression is closely related to the TNM stage of urothelial carcinoma; HER2 three-tier assessment can effectively predict clinical prognosis of urothelial carcinoma.
