Mechanochemical Single-Carbon Insertion into (Iso)quinolines.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
(Iso)quinolines are among the most common heterocycles in US Food and Drug Administration approved drugs, whereas benzoazepines are underrepresented in drug discovery libraries, primarily because of the lack of efficient preparation routes. Therefore, an efficient method of converting (iso)quinolines to benzoazepines by leveraging the chemistries unique to (iso)quinolines to access diverse benzoazepines should be valuable. Herein, we report a mechanochemical skeletal editing protocol for use in carbon-atom insertion into (iso)quinolines to afford the corresponding benzoazepines. This reaction proceeds readily under ambient conditions without the need for metal additives, bulk solvent, or complicated pre-activation processes. Using this user-friendly protocol, we investigate substrate scope, and reaction mechanism. Moreover, benzoazepines undergo light-induced cycloaddition to yield cyclobutene-fused indolines, which can be converted to indoles by selectively removing carbon atoms. The utility of this skeletal transform is further demonstrated through the skeletal editing of pharmaceutically relevant (iso)quinolines.
