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

A nickel-catalysed cross-electrophile coupling (XEC) of 2-halopyridines to form 2,2'-bipyridines and 2,2'-bisquinoline is presented using manganese as the reductant. The method tolerates electron-donating and electron-withdrawing groups around the heterocyclic ring and has been applied to the preparation of homo- and cross-coupled products, including competition experiments. Finally, scaling-up the reaction revealed certain practical considerations that led to deviation from the optimised conditions and provided preliminary mechanistic insights.
