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

Two novel emissive amphiphilic molecules with intramolecular charge transfer character (HAPMP and HAPEOP) were synthesized, and their self-assembled particles were obtained in an aqueous solution. SAXS analysis and TEM observation showed that these self-assemblies exhibited vesicle-like structures. Analysis using the indirect Fourier transformation (IFT) method for their bilayer structures indicated that HAPMP was arranged in a vertical orientation relative to the bilayer plane, whereas HAPEOP adopted a tilted orientation. The maximum emission wavelengths in their vesicle states were red-shifted compared with those in the monomeric state. Time-resolved emission spectroscopy revealed prolonged emission lifetimes, suggesting that they formed an excimer in the bilayers.
