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 RB tumor suppressor is a key regulator of cell cycle progression that is often inactivated in triple-negative breast cancer (TNBC). Recent studies indicate that drugs activating RB have multiple tumor-suppressing effects on the tumor and the tumor microenvironment (TME). Here, we utilize a constitutively active RB protein incapable of being phosphorylated and inactivated by CDKs (RBΔCDK) to assess the intrinsic sufficiency of RB activation on tumor suppression. Expression of RBΔCDK in TNBC cell lines uniformly inhibited proliferation. Transcriptomic analysis revealed suppression of cell cycle genes and the induction of genes associated with interferon response. Similarly, tumor growth and metastasis were suppressed in RBΔCDK-expressing human xenograft and mouse syngeneic tumor models. RB activation was sufficient to dramatically alter the TME, wherein tumor growth suppression was mediated by CD8
