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

Mesoporous gold (mAu) films promise biosensing and electrochemical sensing due to their electroactive surface area, conductivity, and biocompatibility. However, conventional fabrication approaches, including electrodeposition and templating, often require substrate-specific processing and can be challenging to scale, limiting the broader integration of mAu films into practical sensing platforms. Here, we report scalable spin-coating of mAu films on transparent substrates with tunable thickness and uniform mesoporous framework. Electrochemical analyses reveal that additional coating cycles progressively increase the electrochemically active surface area and reduce the interfacial charge-transfer resistance, yielding a corresponding rise in the differential-pulse voltammetric signal, consistent with a mesoporous architecture that promotes efficient redox access and analyte adsorption. To demonstrate biosensing capability, a label-free electrochemical assay for the ovarian cancer-associated microRNA (miRNA) hsa-miR-200c-3p as a model target is developed. The sensor responds monotonically from 1 aM to 10 pM, with a linear calibration (R
