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

Difluorocarbene is a very powerful synthon in organic chemistry, but its reactivity is very challenging to tame. While a few recent studies have pinpointed the potential of transition metals such as Pd and Cu to stabilize and harness difluorocarbene, known examples are confined to relatively classical transformations. Here we report gold(I) difluorocarbenes persisting for hours at 0 °C thanks to ligand-enhanced backdonation. These complexes exhibit unforeseen reactivity with alkenes and 1,3-dienes. The key intermediates, gold(III) metallacycles, have been spectroscopically and crystallographically characterized. Choosing the ligand at gold and operating conditions (thermal or photochemical) enable to direct C─C coupling to the desired product. This novel gold-mediated two-electron redox pathway was leveraged to prepare difluorocyclopentenes, overcoming the intrinsic challenge of [1+4] cycloaddition between carbenes and 1,3-dienes.
