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 increasing demand for miniaturised, high-performance sensing platforms necessitates materials that can be deposited with high spatial precision. Surface-enhanced Raman spectroscopy (SERS) has emerged as a powerful analytical technique, offering significant signal amplification. Nanoporous (np) metals, particularly np Ag, are promising candidates for SERS substrates due to their high surface area and tunable nanostructure. In this study, we compare np Ag fabricated via electrohydrodynamic redox printing (EHD-RP), an additive manufacturing technique with high spatial resolution, to conventionally produced counterparts using physical vapour deposition (PVD). EHD-RP-derived np Ag exhibits comparable SERS performance to PVD samples. Structural analysis reveals that the density of sub-25 nm pores and the degree of structural disorder strongly contribute to enhancement factors. Additionally, EHD-RP-derived np Ag demonstrates excellent stability under varying illumination conditions and effectively catalyses the plasmon-driven dimerisation of 4-nitrobenzenethiol. These results underscore the potential of EHD-RP for fabricating functional nanostructured materials for integrated sensing applications.
