1 · What the graph read from it

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.

2 · The registry

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

The efficacy of immune checkpoint blockade in triple-negative breast cancer (TNBC) is limited by poor CD8⁺ T cell infiltration. Here, we demonstrate that tumor-derived proprotein convertase subtilisin/kexin type 9 (PCSK9) drives CD8⁺ T cell exclusion, and we identify protein arginine methyltransferase 5 (PRMT5) as an important epigenetic regulator responsible for PCSK9 expression in TNBC. Mechanistically, we elucidate that PRMT5-mediated methylation of the chromobox homolog 8 (CBX8) facilitates its interaction with the deubiquitinase USP7, which removes K33-linked ubiquitination on CBX8. This post-translational modification modulates CBX8 function, enabling it to drive the transcriptional upregulation of key downstream targets PCSK9, which inhibits CD8
