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
During cancer cell invasion, integrin undergoes constant endo/exocytic trafficking. It has been found that the recycling ability of integrin β1 through Rab11-controlled long loop pathways is directly associated with cancer invasion. Previous studies showed that gain-of-function mutant p53 regulates the Rab-coupling protein [RCP]-mediated integrin β1 recycling by inactivating tumor suppressor TAp63. So, we were interested to investigate the involvement of miR-205 in this process. In the current study first, we evaluated that the lower expression of miR-205 in MDA-MB-231 cell line is associated with high motility and invasiveness. Further investigation corroborated that miR-205 directly targets RCP resulting in attenuated RCP-mediated integrin β1 recycling. Overexpression of TAp63 validates our in vitro findings. To appraise the anti-metastatic role of miR-205, we developed two in vivo experimental models- xenograft-chick embryo and xenograft-immunosuppressed BALB/c mice. Our in vivo results support the negative effect of miR-205 on metastasis. Therefore, these findings advocate the tumor suppressor activity of miR-205 in breast cancer cells and suggest that in the future development of miR-205-targeting RNAi therapeutics could be a smart alternative approach to prevent the metastatic fate of the disease.
