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 π-bonds in unsaturated organic molecules are typically associated with having well-defined geometries that are conserved across diverse structural contexts. Nonetheless, these geometries can be distorted, leading to heightened reactivity of the π-bond. Although π-bond-containing compounds with bent geometries are well utilized in synthetic chemistry, the corresponding leveraging of π-bond-containing compounds that display twisting or pyramidalization remains underdeveloped. We report a study of perhaps the most notorious class of geometrically distorted molecules that contain π-bonds: anti-Bredt olefins (ABOs). ABOs have been known since 1924, and conventional wisdom maintains that ABOs are difficult or impossible to access. We provide a solution to this long-standing problem. Our study also highlights the strategic manipulation of compounds that display considerable distortion arising from the presence of geometrically constrained π-bonds.
