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
The presence of cancer stem cells (CSCs) is the source of occurrence, aggravation, and recurrence of lung cancer. Accordingly, targeting killing the lung CSCs has been suggested to be an effective approach for lung cancer treatment. In this study, we showed that rapamycin inhibited the mammalian target of rapamycin (mTOR) signal transduction in A549 cells and improved the sensitivity to cisplatin (DDP). The mechanisms involve inhibition of the SOX2 expression, cell proliferation, epithelial-mesenchymal transition (EMT) phenotype, and sphere formation. Interestingly, knocked down SOX2 was a similar effect with rapamycin in A549 sphere. Furthermore, we showed that ectopic expression of Sox2 in A549 cells was sufficient to render them more resistant to rapamycin treatment in vitro. These data suggested that rapamycin inhibited the function of lung CSCs via SOX2. It will be of great interest to further explore the therapeutic strategies of lung cancer.
