High-level Sp1 is Associated with Proliferation, Invasion, and Poor Prognosis in Astrocytoma.

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
Astrocytoma is the most common and the most lethal primary brain tumor in adults. Grade IV glioblastoma is usually refractory to currently available surgical, chemotherapeutic, and radiotherapeutic treatments. The Specificity protein 1 (Sp1) transcription factor is known to regulate tumorigenesis in many cancers. The aim of this study was to investigate the clinicopathologic role of Sp1 protein in the carcinogenesis of astrocytoma. This study analyzed 98 astrocytoma cases treated at Kaohsiung Medical University Hospital during 2002-2012. Clinicopathologic parameters associated with Sp1 were analyzed by chi-square test, Kaplan-Meier analysis, and Cox regression analyses. In vitro proliferation, invasion, and migration were compared between non-siRNA groups and Sp1 siRNA groups. In glioblastoma cells treated with Sp1 siRNA, Western blot was also used to detect expressions of Sp1, Ki-67, VEGF, cyclin D1, E-cadherin, cleaved caspase-3 and Bax proteins. Expression of Sp1 was significantly associated with WHO grade (p = 0.005) and with overall survival time (p < 0.001). Multivariate analysis further revealed that prognosis of astrocytoma was significantly associated with Sp1 expression (p = 0.036) and IDH-1 expression (p < 0.001). In vitro silencing of Sp1 downregulated Sp1, Ki-67, and cyclin D1 but upregulated E-cadherin, Bax, and cleaved caspase-3. These data suggest that Sp1 is a potential prognostic marker and therapeutic target in astrocytoma.
