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

Cyclin-dependent kinase 9 (CDK9) is a serine/threonine kinase involved in the regulation of transcription elongation. An inhibition of CDK9 downregulates a number of short-lived proteins responsible for tumor maintenance and survival, including the antiapoptotic BCL-2 family member MCL-1. As pan-CDK inhibitors under development have faced dosing and toxicity challenges in the clinical setting, we generated selective CDK9 inhibitors that could be amenable to an oral administration. Here, we report the lead optimization of a series of azaindole-based inhibitors. To overcome early challenges with promiscuity and cardiovascular toxicity, carboxylates were introduced into the pharmacophore en route to compounds such as
