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

The elegant hierarchical structures of biomacromolecules have promoted the pursuits of synthetic polymers with ordered monomer sequences and diverse topological architectures, which are in the initial stage. Here, a four-arm star-shaped segmented polyurethane (PU) with a controlled block sequence of amphiphilic seven-segment multifunctional arms containing a disulfide bond was prepared via a grafting-onto strategy, where the sequence-defined arms were synthesized by a diisocyanate-based liquid-phase iterative methodology and then conjugated onto four alkyne-functionalized pentaerythritol cores through click chemistry. The star-shaped PU can self-assemble into micelles in aqueous solution as the linear arm. Moreover, the four-arm star-shaped architecture endows self-assembled micelles with higher stability under various physiological conditions and enhanced redox-responsive performance, making them promising candidates for drug delivery. The experiments show that drug-loaded star-shaped PU micelles possess accelerated stimuli-responsive release profiles, optimized tissue distribution, and improved anticancer efficacy
