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 merocyanine-based amphiphile was self-assembled into ellipsoids that can be disassembled by irradiation with visible light and reassemble in the dark after a delay of ∼70 minutes. Above a threshold concentration, the reassembly occurs when the ratio of protonated merocyanine to spiropyran reaches 7:3, suggesting both isomers are involved in the assembly. The thermal isomerization of the amphiphile when assembled (half-life ∼13 minutes) is significantly slower than that in dilute solution (half-life ∼3.6 minutes). The self-assembly behavior was confirmed by UV-vis spectroscopy, dynamic light scattering (DLS), small-angle neutron scattering (SANS) and small-angle X-ray scattering (SAXS). The delay between the isomerization and the assembly processes can be tuned between minutes and hours by adding differently charged co-surfactants.
