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
Cancer remains one of the leading causes of mortality worldwide, making early detection crucial for improving treatment outcomes. Plasmonic biosensors offer a promising non-invasive approach to detecting cancer cells in their early stages. In this study, we investigate an LSPR-based biosensor employing an innovative plasmonic metamaterial composed of an eight-ring supercell array for cancer detection. The proposed structure features eight ring-shaped cubic supercells, interconnected via a soft-cell interface. Analysis focused on three widely used metals in plasmonics: aluminium, silver, and gold. The evaluation was conducted using the three-dimensional finite difference time domain (FDTD) method. Leveraging the localized surface plasmon resonance (LSPR) effects of the gold nanostructure, dual resonance peaks are achieved in the inductive-capacitive (LC) mode. The designed sensor operates effectively in the near-infrared region, covering the wavelength range of 1000-2100 nm. Sensitivity and figure of merit (FOM) for the first mode are measured at 604 (nm/RIU) and 14.72 (RIU
