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 epidermal growth factor receptor (EGFR) tyrosine kinase is an important therapeutic target in non-small cell lung cancer (NSCLC). However, the continual emergence of resistance mutations in the treatment of EGFR mutation-positive NSCLC with currently approved tyrosine kinase inhibitors warrants the development of next-generation inhibitors. Since research for ATP-competitive EGFR tyrosine kinase inhibitors (TKIs) that extend into the back pocket has been neglected in the recent past, we survey the extent to which such binding functional groups can be incorporated into an ATP-site imidazole scaffold. We find that meta-substituted amide linkers derivatized with fluorine in 2,6-positions and/or a hydroxy group in 3-position of the back pocket phenyl exhibit the highest potency. Structural insights into how the back pocket groups are bound through points of connection provide new directions for the discovery and optimization of inactive conformation targeting agents in EGFR and other kinases.
