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
Purpose: The aggressive nature of a tumor is presumably its inherent one, but different environmental cues can manipulate it in many ways. In this context, the influence of metabolic stresses on tumor behavior needs to be analyzed to understand their far-reaching implications on tumor aggression and dormancy. This work investigates different facets of the tumor, such as tumorigenic capacity, tumor phenotype, and migration, under multiple metabolic stress conditions. Methods: Non-invasive and invasive multicellular spheroids (MTS) were created and subjected to multiple stress conditions, namely glucose, amino acid, and oxygen deprivation. Altered behavior of the MTS has been evaluated in the context of in vitro tumorigenesis, spheroid formation capacity, phenotype, mRNA profile, migration, and recruitment of mesenchymal stem cells. Results: The metabolic stress conditions were observed to negatively impact the in vitro tumorigenesis and spheroid formation process of invasive and non-invasive breast cancer cells. While the stress seemingly influences the growth and phenotype of spheroids, it does not alter the organization of sub-cellular entities significantly. Metabolic stress conditions impact the transcriptomic landscape of hypoxic, angiogenic, ECM deformation, glycolysis shift, and protein starvation-related gene clusters. MTSs do not adhere or migrate under stress, but they exhibit different modalities of migration when rescued. Invasive spheroids, after the rescue, exhibit increased aggressiveness. Furthermore, stressed spheroid was observed to control the migration and recruitment of mesenchymal stem cells. Conclusion: Multiplex metabolic stresses could control the tumorigenesis while influencing the physiology of invasive and non-invasive breast cancer spheroids along with their migration pattern and tumor-stromal crosstalk.
