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 coordination and substitution of hydrocarbon substrates is common for transition metals, and has been demonstrated in a handful of cases with molecules based on heavier p-block elements. By contrast, this behaviour is uncommon for the first-row p-block elements, probably due to the generally irreversible nature of their covalent bond formation. Boranes can loosely bind and, in cooperation with strong Lewis donors, covalently bind and functionalize olefins. However, the single-site reversible coordination and functionalization of olefins by first-row p-block elements remains elusive. Here we present a monovalent boron system able to coordinate olefins and mediate their liberation and functionalization, based on stable and well-defined borylene-olefin π complexes. These molecules are shown to be distinct from their conventional covalently bound form-boriranes-instead better resembling borylenes with π-bound olefins. The high π-complex character of these species suggests a rationale for their unique ability to reversibly bind and functionalize olefins.
