Stage-related transcriptional changes in HR-positive/HER2-negative breast cancer.
Article in NPJ breast cancer, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
It is important to understand how the biology of breast cancer might differ with the burden of disease. Analyzing the expression of cancer-relevant genes with increasing diagnostic stage can provide insight into the changing biology of breast cancer and may also be clinically useful. Here, we evaluated the transcriptional activity according to the stage of breast cancer (American Joint Committee on Cancer, AJCC Stage I to IV) from 1152 patients with hormone receptor-positive HER2-negative breast cancer. Fresh tumor samples were prospectively collected for clinical-translational research with transcriptional profiling. Most transcriptional signatures remained consistent across stage categories, but the significant changes associated with increasing stage were attributed to endocrine escape, decreasing differentiation, increased complexity of signal transduction, and a few metabolic changes. The clinical relevance and implications of these findings are discussed. The expression data from these high-quality samples are a new publicly available resource for researchers.
