Association of copy number alterations with the immune transcriptomic landscape in cancer.
Article in NPJ systems biology and applications, 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
Tumors with high copy number alteration (CNA) burden often respond poorly to immune checkpoint inhibitor therapy. However, how CNAs affect the anti-cancer immune response remains unclear. To address this, we set out to capture the transcriptional effects of CNAs and define a comprehensive landscape of immune-related transcriptional patterns. Hereto, we applied consensus independent component analysis to 294,159 bulk transcriptomic profiles. We demonstrated the predictive power of these patterns for immunotherapy response, their reproducibility across platforms, and their applicability to bulk, single-cell, and spatial transcriptomic data. Our analysis identified both novel inverse and positive associations between high CNA burden and immune-related transcriptional patterns across various cancer types. For example, higher CNA burden correlated with increased immunosuppression, including IL-17-producing cells and regulatory T cells. This resource, along with the classification of these transcriptional patterns as immune-suppressive and immune-stimulatory, may provide insights to improve immunotherapy efficacy in tumors with high CNA burden.
