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

Targeting moieties are often attached to nanocarriers (NCs) using poly(ethylene glycol)-lipids (PEG-lipids) to direct uptake to target cells and organs. However, nanoparticles (NPs) can interact with proteins during systemic circulation, causing PEG-lipids to dissociate or "shed," which limits targeting efficiency. Here, we investigate how lipid chemistry and poly(ethylene glycol)-b-poly(propylene sulfide) (PEG-PPS) NC morphology affect PEG-lipid shedding. We conjugated one fluorophore to the NC and another to the PEG-lipid to track shedding over time. By coupling Förster resonance energy transfer (FRET) and total internal reflection fluorescence microscopy (TIRF) with biological systems, we found that PEG-lipids with stable anchors shed slowly and are consistent across NC morphologies. In contrast, weakly anchored PEG-lipids exhibit morphology-dependent shedding and biodistribution
