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
Introduction: Breast cancer is highly metastatic. One protein that may participate in breast cancer cell migration is the actin motor protein myosin 6 (MYO6), which is likely regulated by the GIPC1 protein. Additionally, septins (SEPTs) appear to participate in breast cancer motility. Here, we investigated the effects of loss of MYO6 on cell morphology, migration, and expression of GIPC1, SEPT2, and SEPT7 in two breast cancer cell lines. Material and Methods: The research material consisted of two breast cancer cell lines, MCF-7 and MDA-MB-231, in which the level of MYO6 was reduced and the effect of knockdown on the migration potential and the expression of GIPC1, SEPT2 and SEPT7 was determined. The levels of these proteins were also analyzed in silico. Results: siRNA-mediated knock down of MYO6 altered the morphology of MCF-7 cells and reduced the expression of GIPC1 and SEPT7 in both MCF-7 and MDA-MB-231 cells. In in silico data, GIPC1, SEPT2, and SEPT7 were all overexpressed in breast cancer tissue samples from patients. Finally, MYO6 knock down impaired migration and adhesion in both MCF-7 and MDA-MB-231 cells. Conclusion: Our study substantiates that downregulation of MYO6 diminishes the migratory abilities of breast cancer cell lines with varying invasiveness. Furthermore, we have demonstrated that decreased MYO6 protein leads to reduced expression of GIPC1, SEPT2, and SEPT7 in breast cancer cells. These findings contribute to a more comprehensive understanding of the pathways influencing breast cancer cell migration, a critical aspect of metastasis.
