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

Although boron compounds appear in many chemical transformations, it is hard to imagine, these usually Lewis acidic, species would act as Lewis bases or even base-catalysts. Here we show that the adduct o-2, formed by the reaction of closo-1,2-dicarbadecaborane(10) with two equivalents of an N-heterocyclic carbene, exhibits superbasic properties with proton affinity surpassing that of the parent carbene as well as commercial superbases. It reacts selectively with C-acids, solvents and water, with its reactivity strongly influenced by substrate pK
