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
backgroundDoxorubicin (Dox) resistance is a primary obstacle for the treatment of osteosarcoma. Meanwhile, β-Elemene was shown to exhibit an anti-proliferative effect on osteosarcoma cells. However, the role of a combination of Dox with β-Elemene on osteosarcoma cells remains unclear. Thus, this study aimed to investigate the role of the combination of Dox with β-Elemene on the proliferation, apoptosis and oxidative stress of Dox-resistance osteosarcoma cells.
methodsCKC-8, EdU staining and flow cytometry assays were used to determine the viability, proliferation and apoptosis of Dox-resistance osteosarcoma cells, respectively. Meanwhile, the expression of antioxidant protein peroxiredoxin-1 (Prx-1) in Dox-resistance osteosarcoma cells was detected with Western blot assay.
resultsIn this study, the inhibitory effects of Dox on the viability and proliferation of Dox-resistance osteosarcoma cells were significantly enhanced by β-Elemene. In addition, the combination of Dox and β-Elemene markedly induced the apoptosis and oxidative stress in Dox-resistance osteosarcoma cells. Moreover, combination treatment notably downregulated the expression of Prx-1 in Dox-resistance osteosarcoma cells, indicating that combination treatment inhibited the antioxidant capacity of Dox-resistance osteosarcoma cells. In vivo experiments confirmed that β-Elemene could enhance the anti-tumor effect of Dox in Saos-2/Dox xenograft model.
conclusionWe found that β-Elemene could reverse Dox resistance in Dox-resistance osteosarcoma cells via inhibition of Prx-1. Therefore, combining Dox with β-Elemene might be considered as a therapeutic approach for the treatment of Dox-resistant osteosarcoma.
