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
Introduction Urothelial carcinomas represent a distinct group of malignancies with a high recurrence potential. Multiple studies have established a set of interactions between the tumor cells of urothelial neoplasms and the extracellular matrix regarding invasion and tumor progression. In the present study, we evaluated the expression of fibroblast growth factor-2 (FGF2) in early-stage urothelial carcinomas of the urinary bladder (pTa and pT1) regarding the invasive potential of these tumors. Materials and methods A retrospective non-clinical approach was utilized for the study. Tumor tissue sections used for the initial diagnosis were stained by immunohistochemical means with an anti-FGF2 antibody and the expression within the extracellular matrix was evaluated using a histo-score (h-score). Statistical parameters regarding tumor invasion, FGF2 expression pattern and levels, patient demographic characteristics, and disease recurrence were analyzed for significance. Results A total of 163 cases were analyzed, with an h-score of 110 determined as the optimal cut-off value for invasive potential regarding FGF2 expression, with a sensitivity of 75.4% and a specificity of 78.9%. No statistical correlation was established between the demographic profile of the patients and the occurrence of disease recurrence. Conclusion Based on our results, the study of tumor-extracellular matrix interactions in regards to FGF2 expression is a promising field, at least in urothelial malignancies of the urinary bladder, in regards to tumor invasive potential, while it remains unestablished how these interactions affect metastatic potential.
