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 daisy chain architecture without a preferred low energy arrangement of the mechanically linked components is presented. The molecular design combines a rigid-rod type oligophenylene ethynylene subunit with an oligoethylene glycol macrocycle that features a bipyridine coordination site. The daisy chain dimer was synthesized via kinetic trapping of the interlocked structure using a Cadiot-Chodkiewicz active metal template reaction. Comparison of the isolated interlocked dimer with its monomeric analogue indicates the presence of a variety of different geometries for the molecular daisy chain. The dynamic sliding motion in the daisy chain is studied by variable temperature UV-vis and nuclear magnetic resonance (NMR) spectroscopy experiments, which point to a highly mobile system even at low temperatures.
