HER2-low breast cancer is immune-cold: insights into tumor-infiltrating immune cells and implications for immunotherapy.
Article in NPJ breast cancer, 2025. 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
This study investigated, for the first time, the association between HER2 expression, immune infiltration inferred by CIBERSORTx, and immunotherapy response in HER2-negative early breast cancer (EBC). Gene expression was analyzed in prospective discovery (n = 104), confirmatory (n = 81), and independent (ABiM, n = 318) cohorts. HER2 expression was measured using a 20-gene signature yielding progressively higher scores from HER2-0 to HER2-low, as routinely defined. Increased HER2 expression was consistently associated with reduced immune-infiltration, especially cytotoxic (CD8
