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

Rapid-release drug delivery systems present a new paradigm in emergency care treatments. Such systems combine a long shelf life with the ability to provide a significant dose of the drug to the bloodstream in the shortest period of time. Until now, development of delivery formulations has concentrated on slow release systems to ensure a steady concentration of the drug. To address the need for quick release system, we created hollow polyacrylate nanocapsules with nanometer-thin porous walls. Burst release occurs upon interaction with blood components that leads to escape of the cargo. The likely mechanism of release involves a conformational change of the polymer shell caused by binding albumin. To demonstrate this concept, a near-infrared fluorescent dye indocyanine green (ICG) was incorporated inside the nanocapsules. ICG-loaded nanocapsules demonstrated remarkable shelf life in aqueous buffers with no release of ICG for twelve months. Rapid release of the dye was demonstrated first in vitro using albumin solution and serum. SEM and light scattering analysis demonstrated the retention of the nanocapsule architecture after the release of the dye upon contact with albumin. In vivo studies using fluorescence lifetime imaging confirmed quick discharge of ICG from the nanocapsules following intravenous injection.
