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

A practical surface-enhanced Raman scattering (SERS) substrate is reported constructed by depositing Ag nanoparticle dimers (Ag NDs) onto a polydimethylsiloxane (PDMS) film with macroscopic cavity arrays (MCA). This design integrates the synergistic advantages of large-aperture and shallow-depth MCA, as well as Ag NDs with abundant nanogaps, achieving a well-balanced combination of sensitivity, uniformity, and operability for rapid testing. The open MCA structure, fabricated using commercial toothbrush bristles as a template, not only facilitates analyte enrichment through spatial confinement but also serves as a patterned scaffold for depositing densely plasmonic Ag dimer arrays, which generates high-density SERS hotspots. The optimized Ag NDs@MCA substrate exhibits desirable SERS performance, including good sensitivity, satisfactory uniformity, and reliable batch-to-batch reproducibility. Furthermore, the naked-eye-distinguishable cavities allow direct visual positioning of detection sites, significantly simplifying testing operation. Coupled with a portable Raman spectrometer, the as-prepared SERS substrate achieved fast trace determination of malachite green (10⁻
