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 fabrication of inorganic-based nanopatterns with feature sizes below 3 nm remains a fundamental challenge in nanoscience and advanced manufacturing. Existing approaches, including extreme ultraviolet lithography, block copolymer self-assembly, and colloidal nanocrystal patterning, struggle to reliably achieve such dimensions while maintaining long-range order and structural fidelity. Here, we present a pattern transfer technique from a supramolecular dendrimer templating strategy that enables highly ordered sub-3 nm ruthenium-based nanostructures over large areas (1 µm × 1 µm). The pristine dendrimer template forms a hexagonally packed cylindrical morphology with sub-5 nm periodicity, exhibiting structural stability and long-range order. Thermal annealing induces cooperative self-assembly into a single-domain array, which is selectively stained with RuO
