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

Acute myocardial infarction (AMI) causes cardiac tissue damage and creates a transient leaky vasculature, which is an attractive target for intravascular therapeutics. Nanomaterials have the potential to deliver therapeutics to the injured heart, yet the influence of particle size, shape, and surface decoration on infarct localization has not been systematically examined. Here, we evaluated a self-assembling peptide platform that can be tuned to form high aspect ratio nanofibers or globular nanoparticles by modifying the β sheet forming domain. This platform has tunable nanofiber length distribution via sonication and aging as well as surface decoration via targeting peptides. In a rat model of AMI, the incorporation of a type IV collagen targeting peptides significantly increased localization of the nanofibers to the injured leaky vasculature while globular peptides diffuse through and targeted the infarcted myocardium. These results demonstrate that this modular peptide nanomaterial can be tuned via geometry and surface moieties to either target to the compromised vasculature components or infiltrate the infarct. This study establishes size, shape, and surface decoration as critical features for effective intravascular nanomaterial delivery after AMI.
