Cryo-ET comparison of the hierarchical ultrastructure of silkworm, spider, and artificial silk fibers.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Spider and silkworm silks are renowned for their exceptional mechanical properties, which arises from their ultrastructural organization. However, this architecture remains incompletely understood. Here, we apply cryo-electron tomography to examine the hierarchical organization of silkworm, spider, and artificial silks. In silkworm silk, we observe nanofibrils of ~3.6 nm in diameter, interconnected by abundant bridges and representing the smallest fibrillar features currently accessible by cryo-ET. These nanofibrils align with the fiber axis and are organized into a herringbone pattern, with stacked layers building the micron-scale filament. Spider silk displays densely packed nanofibrils with near-perfect axial alignment and minimal voids. In contrast, silkworm silk shows regionally heterogeneous gaps, whereas artificial silk lacks the ordered packing characteristic of natural materials. These observations provide a structural basis for understanding silk formation and may guide future biomimetic fiber design.
