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
Matrix stiffness is a key factor in breast cancer progression, but its impact on cell function and response to treatment is not fully understood. Here, we developed a stiffness-tunable hydrogel-based three-dimensional system that recapitulates the extracellular matrix and physiological properties of human breast cancer in vitro. Adjusting the ratio of GelMA to PEGDA in the hydrogel formulation enabled the fine-tuning of matrix stiffness across a range of 7 to 52 kPa. Utilizing this three-dimensional (3D) hydrogel platform for a breast cancer cell culture has enabled precise functional evaluations. Variations in matrix stiffness resulted in significant changes in the morphology of breast cancer cells after 2 weeks of incubation. The analysis of transcriptomic sequencing revealed that the 3D microenvironment significantly changed the expression of a wide panel of transcriptomic profiles of breast cancer cells in various matrix stiffness. Gene Ontology analysis further suggested that specific biological functions could potentially be linked to the magnitude of the matrix stiffness. According to our findings, extracellular matrix rigidity modulates the sensitivity of breast cancer cells to paclitaxel and adriamycin. Notably, the expression of ABCB1 and YAP1 genes may be upregulated in the 3D culture environment, potentially contributing to the increased drug resistance observed in breast cancer cells. This work aims to establish facile adjustable hydrogels to deepen insights into matrix rigidity effects on breast cancer cells within 3D microenvironments, highlighting the critical role of extracellular matrix stiffness in modulating cell-matrix interactions.
