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
Three-dimensional (3D) assembly of colloidal metal nanoparticles for plasmonic detections has been prepared by Langmuir-Blodgett (LB) deposition. However, due to the small focal volume of an incident light, it suffers from laser spot-to-spot variations in near-field intensities, which undermines signal uniformity, thereby hindering its widespread use. Here, a facile and scalable method to fabricate focal volume-comparable is presented, uniform 3D architectures of plasmonic hotspots by devising the force-assisted, capillary-mediated stacking of colloidal metal nanoparticles. By deploying only a few pN per nanoparticle, it is shown that the method quickly produces multiple monolayers with lateral sizes in the submillimeter range, in which surface uniformity with a small variation of 4% is improved by ≈30% compared to the LB deposition. The simulation suggests that the volume fraction of electromagnetic field enhancement increases with increasing the number of layers, and its intensity can be maximized by more than 100% by simply stacking the monolayers. Additionally, tailoring the size of the void of the 3D assembly leads to a four orders of magnitude increase in the sensitivity of the Raman detection. It is indicated that the method can greatly improve the practical utility of colloidal metal nanoparticles for sensing applications from biomedicine to biomanufacturing.
