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

A photoinduced ring-opening radical C2-phosphinylation of bicyclo[1.1.0]butanes with secondary phosphine oxides by cobaloxime catalysis is described. This reaction features mild conditions, wide substrate scope, and high site-selectivities, producing a diverse range of phosphorylated cyclobutenes in good yields with hydrogen evolution. The mechanism studies indicate that this reaction likely proceeds through a bicyclo[1.1.0]butane isomerization and dehydrogenative allylic phosphinylation process.
