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 positive transcription elongation factor b (P-TEFb) complex, composed of CDK9 and cyclin T isoforms (T1, T2a and T2b), is critical for gene transcription, positioning CDK9 as a very promising oncology target. However, the development of selective and clinically effective small-molecule CDK9 inhibitors has proven challenging. To overcome this limitation, we designed a series of highly efficient and selective P-TEFb degraders by conjugating the CDK9 inhibitor SNS032 with the mouse double minute 2 (MDM2) ligand RG7388. Our lead compound,
