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 high-performance optical fiber surface plasmon resonance (SPR) biosensor for the determination of dopamine (DP) is reported based on gold nanocone arrays combined with gold nanoparticles (AuNPs). The sensor was fabricated via thermal nanoimprinting, gold sputtering, and single-stranded DNA-assisted AuNPs immobilization to form gap hotspots. Finite element simulation and experimental results verified strong electromagnetic field enhancement via extraordinary optical transmission and SPR-LSPR coupling. The sensor achieved a detection limit of 2.7 × 10
