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

We introduce a new 3,5-diphenylpyridinium motif that can be readily installed on α-tertiary alkyl amines and enables effective deamination. This advance overcomes the limitation that Katritzky pyridinium salts cannot be accessed from α-tertiary alkyl amines. Use of this 3,5-diphenylpyridinium salt enables a nickel-catalyzed reductive alkylation of Michael acceptors to construct quaternary carbons with a broad range of tertiary alkyl groups. Density functional theory (DFT) calculations were used to understand the surprising reactivity difference between adamantyl and other tertiary alkyl groups.
