Machine learning-enhanced multi-band metamaterial sensor for early detection of neurological disorders.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study presents a square enclosed double octagonal shaped metamaterial absorber for the detection of initial neurological conditions. The size is very compact ([Formula: see text]) and achieves an absorption value over 99% for frequencies of 4.632 THz, 6 THz, and 7.384 THz. The key focus of the study is sensitivity, which is excellent for all of the peaks, which are 1.5 THz/RIU, 1.5 THz/RIU, and 1.8 THz/RIU, indicating its superior performance across multiple frequency bands. Furthermore, the q factor values are 22.21, 29.41, and 33.81, and the fom values are 7.19, 7.35, and 8.24 for the three frequency peaks, respectively, supporting its reliability in sensing. The electric field, magnetic field, and surface current are analyzed, and an equivalent circuit is created and evaluated for design validation. Additionally, machine learning techniques were employed to optimize and predict the structure’s performance, with the GradientBoosting model demonstrating a reduction of up to 60% in simulation time while maintaining high predictive accuracy. The overall performance and sensing tests across various brain tissues demonstrate excellent results, indicating that this sensor may be an ideal choice for the detection of early-stage neurological disorders.
