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

objectiveTo develop a simple, rapid and cheap catalytic method for methoxylation of aryl halides for late-stage functionalization and demonstrate its utility in isotopic labelling.

resultsA ligand-free, microwave-assisted method for methoxylation of aryl halides using copper(II) hydroxide as catalyst has been explored. The new method is simple and cheap, afforded synthetically useful yields in some cases, but does not seem to give generally higher yields in more substituted systems. The viability of isotopic labelling using the method has been demonstrated by 13C-incorporation at the methoxy group.
