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
This study is designed to examine the radiosensitizing effects of coexpression of doublecortin (DCX) and secreted protein and rich in cysteine (SPARC). Previously, we showed that downregulation of SPARC by small interfering RNA increased radioresistance of U-87MG glioma cells. Therefore, overexpression of SPARC might increase radiosensitivity of glioma cells. But SPARC has been shown to promote glioma cell invasion both in vitro and vivo. In order to radiosensitize glioma cells without stimulating invasion, we chose DCX, which is a well-characterized anti-tumor gene, to coexpress with SPARC. An adenovirus-mediated double gene expression system was constructed and applied to U251 and A172 glioma cell lines. Our data showed that coexpression of DCX and SPARC collaboratively diminished radioresistance of glioma cells, interfered with cell cycle turnover and increased irradiation-induced apoptosis. In addition, transwell assay revealed that coexpression was able to counteract the invasion-promoting effects of SPARC, and even inhibited intrinsic invasion, evidenced by less invading cells in double gene overexpressed group than that of control adenovirus-treated group. In conclusion, genetic engineering combining two or more genes might be a more effective method to overcome radioresistance of glioma cells.
