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

Cryoelectron tomography (cryo-ET) enables three-dimensional visualization of molecular structures within tissue and intact cells, providing a powerful tool for studying the spatial organization of biological components at nanometer resolution. Realizing this potential, particularly for submegadalton complexes, is facilitated by fiducial-based labeling. Gold nanoparticles (AuNPs) have emerged as powerful electron-dense labels for cryo-ET, but multiplexing using only conventional monomeric AuNPs is challenging, limiting their application in multitarget studies. Here, we describe functionalized dimeric AuNPs with a precisely defined size range applied to bioimaging, enabling multiplexed labeling by allowing reliable discrimination between monomeric and dimeric AuNPs, thereby supporting identification of distinct molecular targets within the same cryotomogram. Each dimer consists of two covalently linked gold particles of approximately 2.6 nm diameter separated by a defined spacing of about 1.4 nm, with high structural homogeneity validated by small-angle X-ray scattering (SAXS) and electron microscopy. The anti-GluN1 Fab, which targets the
