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

Water-to-oil charge transfer (CT) across weak C-H···O hydrogen bonds is localized for hexane and hexadecane, and is too small to explain oil-droplet stability and electrokinetic experiments. Collective intraphase density rearrangements should not be confused with interfacial CT. Spectroscopic evidence cannot simultaneously imply weak CT for the C-H blue shift and large CT for the O-H/D red shift. A weakness of the C-H···O CT mechanism is that it can't explain other oil emulsion chemistry without this specific chemical motif.
