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

Rhodium complexes supported by fluorinated tris- and bis-(pyridyl)borates effectively catalyze redox-neutral C─C silylation of cyclopropyl acetates, producing the umpolung, silicon-containing heterocyclic products, dioxasilolanes, in good yields with high regio- and diastereoselectivity. The enhanced performance arises from the weakly donating ability of the fluorinated ligands, along with the considerable steric bulk of the poly(pyridyl)borates, which together govern both reactivity and selectivity. Additionally, rhodium(I)-cyclooctadiene and rhodium(I)-norbornadiene complexes supported by poly(pyridyl)borate ligands have been isolated and characterized. X-ray crystal structures show that in these square planar complexes, poly(pyridyl)borate ligands bind to rhodium in a κ
